Account of Zayd ibn ʿAmr ibn Nufayl, may Allah have mercy on him:
Musa ibn ʿUqbah said: Salim informed me that he heard his father relate from the Messenger of Allah ﷺ that, before the Revelation, the Prophet ﷺ met Zayd ibn ʿAmr ibn Nufayl in the lower part of Baldah. The Prophet offered him a food-tray that contained meat, but Zayd refused and said, “I do not eat anything slaughtered on their stone altars; I eat only that over which the name of Allah has been invoked.”
Al-Bukhari recorded this report and added at its end: “Zayd used to censure Quraysh for their sacrifices, saying, ‘The sheep is created by Allah; He sends water down from the sky and causes vegetation to grow for it from the earth, yet you slaughter it without mentioning the name of Allah!’ He said this in condemnation and out of reverence for Allah.”
Al-Bukhari further said: Musa told me, ‘Salim ibn ʿAbd Allah— and I know of no one from whom he heard this except Ibn ʿUmar—related that Zayd ibn ʿAmr ibn Nufayl travelled to Syria in search of the true religion. He met a Jewish scholar and asked about their faith, saying, “Perhaps I will adopt your religion.” The scholar replied, “You will never be on our religion until you accept your share of Allah’s wrath.” Zayd said, “It is precisely Allah’s wrath that I flee from, and as long as I am able, I will never carry any of it. Can you direct me to something else?” The scholar answered, “I know of nothing except that you become a hanif.” Zayd asked, “What is a hanif?” He replied, “The religion of Abraham; he was neither a Jew nor a Christian and worshipped none but Allah.”
Zayd then met a Christian scholar and said the same to him. The scholar said, “You will not be on our religion until you take your share of Allah’s curse.” Zayd replied, “It is Allah’s curse that I am running from,” and the scholar answered him exactly as the Jew had. When Zayd heard what they said about Abraham, he left; and when he reached the open, he raised his hands and proclaimed, “O Allah, I bear witness before You that I follow the religion of Abraham.” Al-Bukhari also narrated it in this form.
