The Messenger of Allah ﷺ said, "Allah, the Mighty and Majestic, will say, 'Adam!' He will reply, 'Here I am at Your service, and all good is in Your hands.' Allah will say, 'Send forth the company of the Fire.' Adam will ask, 'What is the company of the Fire?' Allah will answer, 'Out of every thousand, nine hundred and ninety-nine.' That is when the young will turn gray, 'and every pregnant woman will deliver her burden, and you will see people intoxicated, though they are not intoxicated, but the punishment of Allah is severe' [Hajj 22:2]."This weighed heavily upon them, and they said, "Messenger of Allah, which one of us will be that man?"He said, "Rejoice, for from Gog and Magog there will be a thousand, and from you only one man."Then he said, "By the One in whose hand my soul is, I truly hope that you will be a quarter of the people of Paradise."So we praised Allah and said takbir.Then he said, "By the One in whose hand my soul is, I truly hope that you will be a third of the people of Paradise."So we praised Allah and said takbir.Then he said, "By the One in whose hand my soul is, I truly hope that you will be half of the people of Paradise. Your likeness among the nations is like that of a single white hair on the hide of a black bull, or like a small mark on the foreleg of a donkey."
قال رسول الله ﷺ: يقول الله عزوجل: يا آدم! فيقول: لبيك وسعديك، والخير في يديك، قال: يقول أخرج بعث النار. قال: وما بعث النار؟ قال: من كل ألف تسعمائة وتسعة وتسعين. قال: فذاك حين يشيب الصغير، {وتضع كل ذات حمل حملها وترى الناس سكرى وما هم بسكرى ولكن عذاب الله شديد}. قال: فاشتد ذلك عليهم. قالوا: يا رسول الله! أينا ذلك الرجل، فقال: أبشروا، فإن من يأجوج ومأجوج ألفا ومنكم رجل قال: ثم قال: والذي نفسي بيده، إني لأطمع أن تكونوا ربع أهل الجنة. فحمدنا الله، وكبرنا. ثم قال: والذي نفسي بيده، إني لأطمع أن تكونوا ثلث أهل الجنة. فحمدنا الله، وكبرنا، ثم قال: والذي نفسي بيده، إني لأطمع أن تكونوا شطر أهل الجنة، إن مثلكم في الأمم كمثل الشعرة البيضاء في جلد الثور الأسود، أو كالرقمة في ذراع الحمار.
Bukhari reported it in the Tafsir (4741), and Muslim in the Faith (222), both through Amash, who said, Abu Salih narrated to us, from Abu Saeed Khudri, who said, then he mentioned it. The wording given is Muslim's, and Bukhari's wording is similar. His statement, "That is when hair turns grey..." carries a meaning consistent with the words of Allah Almighty, "So how will you guard yourselves, if you disbelieve, against a day that will turn children grey-haired" [Muzzammil 73:17].
