Warrad, the freed slave of Mughira bin Shu'bah, reported: Mughira bin Shu'bah wrote to Mu'awiyah (it was Warrad who wrote this letter for him, i. e. Mughira): I heard the Messenger of Allah (ﷺ) saying: "When the salutation is pronounced." and the rest of the hadith is the same except this that he made no mention of:" He is Potent over everything."

Warrad, the scribe of Mughira bin Shu'bah, reported: Mu'awiyah wrote to Mughira: Write to me anything which you heard from the Messenger of Allah (ﷺ) . So he (Mughira) wrote to him (Mu'awiyah): I heard the Messenger of Allah (ﷺ) uttering (these words) at the completion of prayer: "There is no god but Allah. He is alone and there is no partner with Him. Sovereignty belongs to Him and to Him is praise due and He is Potent over everything. O Allah! no one can withhold what Thou givest, or give what Thou withholdest, and riches cannot avail a wealthy person with Thee."

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.)

Ibn Mas'ud reported Allah's Messenger (ﷺ) as saying: Wretched is the man who says: I forgot such and such a sura, or I forget such and such a verse, but he has been made to forget.

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).
Farwa' bin Naufal reported on the authority of 'A'isha that Allah's Messenger (ﷺ) used to supplicate (in these words): "O Allah, I seek refuge in Thee from the evil of what I did and from the evil of what I did not."
