Ubayy Ibn Ka'b reported: I asked the Messenger of Allah (ﷺ) about a man who has sexual intercourse with his wife, but leaves her before orgasm. Upon this he (the Holy Prophet) said: He should wash the secretion of his wife, and then perform ablution and offer prayer.

Ubayy ibn Ka'b narrated it from the Messenger of Allah (ﷺ) that he said: If a person has sexual intercourse with his wife, but does not experience orgasm, he should wash his organ and perform an ablution.

Ubayy bin Ka'b reported: There was a man, and I do not know of any other man, whose house was farther than his from the mosque and he never missed the prayer (in congregation). It was said to him or I said to him: If you were to buy a donkey you could ride upon it in the dark nights and in the burning sand. He said: I do not like my house to be situated by the side of the mosque, for I (eagerly) desire that my steps towards the mosque and back from it, should be recorded when I return to my family. Upon this the Messenger of Allah (ﷺ) said: Allah has gathered all (rewards) for you.

Ubayy bin Ka'b reported: There was a person among the Ansar whose house was situated at the farthest end of Madinah, but he never in missed any prayer along with the Messenger of Allah (ﷺ) . We felt pity for him and said to him: O, so and so, had you bought a donkey it would have saved you from the burning sand and would have saved you from the reptiles of the earth. He said: Listen! by Allah, I do not like my house to be situated by the side of Muhammad (ﷺ) . I took (these words of his) ill and came to the Apostle of Allah (ﷺ) and informed him about (these words). He (the Holy Prophet) called him and he said exactly like that (which he had mentioned to Ubbay bin Ka'b), but made a mention of this (also) that he wanted a reward for his steps. Upon this the Apostle of Allah (ﷺ) said: In fact for you is the reward which you expect.

Zirr (b. Hubaish) reported: I heard from Ubayy bin Ka'b a statement made by 'Abdullah bin Mas'ud in which he said: He who gets up for prayer (every night) during the year will hit upon Lailat-ul-Qadr. Ubayy said: By Allah I there is no god but He, that (Lailat-ul-Qadr) is in Ramadhan (He swore without reservation:) By Allah, I know the night; it is the night on which the Messenger of Allah (ﷺ) commanded us to pray. It is that which precedes the morning of twenty-seven and its indication is that the sun rises bright on that day without rays.

Ubayy b Ka'b reported: By Allah, I know about Lailat-ul Qadr and I know it fully well that it is the twenty-seventh night (during Ramadan) on which the Messenger of Allah (ﷺ) commanded us to observe prayer. (Shu'bah was in doubt about these words:" the night on which the Messenger of Allah (ﷺ) [may peace be upon him] commanded us to observe the prayer." This has been transmitted to me by a friend of mine.)

Ubayy bin Ka'b said: Allah's Messenger (ﷺ) said: O Abu' al-Mundhir, do you know the verse from the Book of Allah which, according to you, is the greatest? I said: Allah and His Apostle (ﷺ) know best. He again said: Abu'l-Mundhir, do you know the verse from the Book of Allah which, according to you, is the greatest? I said: Allah, there is no god but He, the Living, the Eternal. Thereupon he struck me on my breast and said: May knowledge be pleasant for you, O Abu'l-Mundhir!

Ubayy bin Ka'b reported: I was in the mosque when a man entered and prayed and recited (the Qur'an) in a style to which I objected. Then another man entered (the mosque) and recited in a style different from that of his companion. When we had finished the prayer, we all went to Allah's Messenger (ﷺ) and said to him: This man recited in a style to which I objected, and the other entered and recited in a style different from that of his companion. The Messenger of Allah (ﷺ) asked them to recite and so they recited, and the Apostle of Allah (ﷺ) expressed approval of their affairs (their modes of recitation). and there occurred In my mind a sort of denial which did not occur even during the Days of Ignorance. When the Messenger of Allah (ﷺ) saw how I was affected (by a wrong idea), he struck my chest, whereupon I broke into sweating and felt as though I were looking at Allah with fear. He (the Holy Prophet) said to me: Ubayy. a message was sent to me to recite the Qur'an in one dialect, and I replied: Make (things) easy for my people. It was conveyed to me for the second time that it should be recited in two dialects. I again replied to him: Make affairs easy for my people. It was again conveyed to me for the third time to recite in seven dialects And (I was further told): You have got a seeking for every reply that I sent you, which you should seek from Me. I said: O Allah! forgive my people, forgive my people, and I have deferred the third one for the day on which the entire creation will turn to me, including even Ibrahim (peace be upon him) (for intercession).

Ubayy bin Ka'b reported that he was sitting in a mosque that a person entered it and he observed prayer, and made recitation, the rest of the hadith is the same.

Ubayy bin Ka'b reported that the Apostle of Allah (ﷺ) was near the tank of Banu Ghifar that Gabriel (ؑ) came to him and said: Allah has commanded you to recite to your people the Qur'an in one dialect. Upon this he said: I ask from Allah pardon and forgiveness. My people are not capable of doing it. He then came for the second time and said: Allah has commanded you that you should recite the Qur'an to your people in two dialects. Upon this he (the Holy prophet) again said: I seek pardon and forgiveness from Allah, my people would not be able to do so. He ( Gabriel (ؑ)) came for the third time and said: Allah has commanded you to recite the Qur'an to your people in three dialects. Upon this he said: I ask pardon and forgiveness from Allah. My people would not be able to do it. He then came to him for the fourth time and said: Allah has commanded you to recite the Qur'an to your people in seven dialects, and in whichever dialect they would recite, they would be right.

Zirr bin Habaish reported: I asked Ubayy bin Ka'b (RA) : Your brother (in faith) Ibn Mas'ud says: He who stands (for the night prayer) throughout the year would find Lailat-ul-Qadr, whereupon he said: May Allah have mercy upon him; (he said these words) with the intention that people might not rely only (on one night), whereas he knew that it (Lailat-ul-Qadr) is in the month of Ramadan and it is the twenty-seventh night. He then took oath (without making any exception, i. e. without saying Innsha Allah) that it was the twenty-seventh night. I said to him: Abu Mundhir, on what ground do you say that? Thereupon he said: By the indication or by the sign which the Messenger of Allah (ﷺ) gave us, and that is that on that day (the sun) would rise without having any ray in it.

Zirr bin Hubaish reported that Ubayy bin Ka'b (RA) said about Lailat-ul-Qadr: By Allah, I know well about it. Shu'bah said: To the best of my knowledge it was the twenty-seventh night for which the Messenger of Allah (ﷺ) commanded us to stand for prayer. Shu'bah doubted these words: That it was the night for which the Messenger of Allah (ﷺ) commanded us to stand for prayer. And (he further) said: This was narrated to me by a friend of mine from him (the Holy Prophet).

Salama bin Kuhail reported: I heard Sowaid bin Ghafala say: I went out, and also Zaid bin Suhan and Salman bin Rabi'a for Jihad, and I found a whip and took it up. They said to me: Leave it. I said: No, but I will make announcement of it and if its owner comes (then I will return that), otherwise I will use it, and I refused them. When we returned from Jihad, by a good fortune for me, I performed Pilgrimage. I came to Madinah and met Ubayy bin Ka'b, and related to him the affair of the whip and their opinion (the opinion of Zaid bin Suhan and Salman bin Rabi'a) about it (i. e. I should throw it). Thereupon he said: I found a money bag during the lifetime of Allah's Messenger (ﷺ) which contained one hundred dinars. I came to him along with it, and he said: Make an announcement of it for one year; so I announced it, but did not find anyone who could (claim it after) recognising it. I again came to him and he said: Make announcement for one year. So I made announcement of it, but I found none who could recognise it. I came to him he said: Make announcement of it for one year. I made announcement of that but did not find one who could recognise it, whereupon he said: Preserve (in your mind) its number, its bag and its strap, and if its owner comes (then return that to him), otherwise make use of it. So I made use of that. I (Shu'bah) met him (Salama bin Kuhail) after this in Makkah, and he said: I do not know whether he said three years or one year.

Abu Musa Ash'ari reported that he went to 'Umar bin Khattab and greeted him by saying: As-Salamu-'Alaikum, here is 'Abdullah bin Qais (RA) , but he did not permit him (to get in). He (Abu Musa Ash'ari) again greeted him with as-Salamu-'Alaikum and said: Here is Abu Musa, but he (Hadrat 'Umar) did not permit him (to get in). He again said: As-Salam-u-'Alaikum, (and said) here is Ash'ari, (then receiving no response he came back). He (Hadrat 'Umar) said: Bring him back to me, bring him back to me. So he went there (in the presence of Hadrat 'Umar) and he said to him: Abu Musa, what made you go back, while we were busy in some work? He said: I heard Allah's Messenger (ﷺ) as saying: Permission should be sought thrice. And if you are permitted, (then get in), otherwise go back. He said: Bring witness to this fact, otherwise I shall do this and that, i. e. I shall punish you. Abu Musa went away and 'Umar said to him (on his departure): If he (Abu Musa) finds a witness he should meet him by the side of the pulpit in the evening and if he does not find a witness you would not find him there. When it was evening he (Hadrat 'Umar) found him (Abu Musa) there. He (Hadrat 'Umar) said: Abu Musa, have you been able to find a witness to what you have said? He said: Yes. Here is Ubayy bin Ka'b, whereupon he (Hadrat 'Umar) said: Yes, he is an authentic (witness). He (Hadrat 'Umar) said: Abu Tufail (the kunya of Ubayy bin Ka'b), what does he (Abu Musa) say? Thereupon he said: Ibn Khattab, I heard Allah's Messenger (ﷺ) as saying so. Do not prove to be a hard (task-master) for the Companions of Allah's Messenger (ﷺ) , whereupon he Hadrat 'Umar said: Hallowed be Allah. I had heard something (in this connection), but I wished it to be established (as an undeniable fact).

Ibn 'Abbas has reported this hadith on the authority of Ubayy bin ka'b that Allah's Apostle (ﷺ) used to recite this.

'Utba bin Mas, ud reported that 'Abdullah bin 'Abbas contended with Hurr bin Qais bin Hisn al-Fazari about the companion of Moses (ؑ) (peace be upon him). Ibn 'Abbas said that he was Khadir. There happened to pass Ubayy bin Ka'b Ansari. Ibn Abbas (RA) called him and said: Abu Tufail, come to us. There has been a difference of opinion between me and my friend about the companion of Moses (ؑ) whom he wanted to meet on the way. Did hear anything from Allah's messenger (ﷺ) making a mention of anything? Ubayy said: I heard Allah's Messenger (may Peace be upon him) as saying: As Moses (ؑ) was amongst the group of Bani Isra'il, there came to him a person and he said to him: Do you know anyone having better knowledge than you? Moses (ؑ) said: No. Thereupon Allah revealed to Moses (ؑ): Of course, there is amongst Our servants Khadir (who has better knowledge) than you. Moses (ؑ) asked the way of meeting him. Allah made the fish a sign and it was said to him: Where you miss the fish return to that (place) and you will soon find him. So Moses (ؑ) moved on as Allah wished him to move on. He then said to his young companion: Bring for us the breakfast. Thereupon that young man said to Moses (ؑ), when he asked him for the breakfast: Don't you see that as we had reached the Sakhra I forgot the fish and nobody made it forget (in our mind) but the satan that I should remind you of it? Moses (ؑ) said to that young man: This was what we wanted. So they retraced their steps and met Khadir and the events which followed have been described in His Book except that Yunus (the narrator) said that he followed the traces of fish in the ocean.

Ubayye bin Ka'b reported that Allah's Messenger (ﷺ) said: The young man whom Khadir killed was a non-believer by his very nature and had he survived he would have involved his parents in defiance and unbelief.

Ubayy bin Ka'b reported that the words of Allah, the Exalted and Glorious: "We will, surely, make them taste the lesser punishment before the severer punishment (that they may return)" (xxxii. 21) imply the torments of the world. (victory of) Rome, seizing (of the Makkahns), or smoke. And Shalba was in doubt about seizing or smoke.

'Abdullah bin Harith bin Naufal reported: I was standing along with Ubayy bin Ka'b and he said: The opinions of the people differ in regard to the achievement of worldly ends. I said: Yes, of course. Thereupon he said: I heard Allah's Messenger (ﷺ) as saying: The Euphrates would soon uncover a mountain of gold and when the people would hear of it they would flock towards it but the people who would possess that (treasure) (would say): If we allow these persons to take out of it they would take away the whole of it. So they would fight and ninety-nine out of one hundred would be killed. Abu Kamil in his narration said: I and Abu Ka'b stood under the shade of the battlement of Hassan.
