A caravan of merchandise arrived at Medina on a Friday while we were with the Prophet (ﷺ) All the people left (the Prophet (ﷺ) and headed for the caravan) except twelve persons. Then Allah revealed:-- 'But when they see some bargain or some amusement they disperse headlong to it.' ..(62.11)

← Previous Hadith The Prophet (ﷺ) said. Then some men from these people would attain it."

Sahih al-Bukhari Book 65, Hadith 418 Next Hadith → While I was taking part in a Ghazwa. I heard `Abdullah bin Ubai (bin Abi Salul) saying. "Don't spend on those who are with Allah's Messenger (ﷺ), that they may disperse and go away from him. If we return (to Medina), surely, the more honorable will expel the meaner amongst them." I reported that (saying) to my uncle or to `Umar who, in his turn, informed the Prophet (ﷺ) of it. The Prophet (ﷺ) called me and I narrated to him the whole story. Then Allah's Messenger (ﷺ) sent for `Abdullah bin Ubai and his companions, and they took an oath that they did not say that. So Allah's Messenger (ﷺ) disbelieved my saying and believed his. I was distressed as I never was before. I stayed at home and my uncle said to me. "You just wanted Allah's Messenger (ﷺ) to disbelieve your statement and hate you." So Allah revealed (the Sura beginning with) 'When the hypocrites come to you.' (63.1) The Prophet (ﷺ) then sent for me and recited it and said, "O Zaid! Allah confirmed your statement."
