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!

Abu Musa al-Ash'ari reported: We came to Allah's Messenger (ﷺ) requesting him to provide us with riding camels. He (the Holy Prophet) said: There is nothing with me with which I should equip you. By Allah, I would not provide you with (riding camels). Then Allah's Messenger (ﷺ) sent to us three camels with spotted bumps. We said: We came to Allah's Messenger (ﷺ) asking him to equip us with riding animals. He took an oath that he could not equip us. We came to him and informed him. He said: By Allah, I do not take an oath, but when I find the other thing better than that, I do that which is better.
Abu Musa reported: We walked on foot and came to Allah's Apostle (ﷺ) (may peace he upon him) asking him to provide us with mounts. The rest of the hadith is the same.
Abu Hassan reported: I said to Abu Hurairah (RA) that my two children had died. Would you narrate to me anything from Allah's Messenger (ﷺ) a hadith which would soothe our hearts in our bereavements? He said: Yes. Small children are the fowls of Paradise. If one of them meets his father (or he said his parents) he would take hold of his cloth, or he said with his hand as I take hold of the hem of your cloth (with my hand). And he (the child) would not take off (his hand) from it until Allah causes his father to enter Paradise.
