The Prophet ﷺ said, "On the Day of Resurrection, Allah the Exalted will say to Adam, 'Stand and send forth from your descendants nine hundred and ninety-nine to the Fire and one to Paradise.'"His companions wept at this.Then the Messenger of Allah ﷺ said to them, "Raise your heads. By the One in whose hand is my soul, my nation among the nations is but like a single white hair on the hide of a black bull."This brought them relief.
عن النبي ﷺ قال: إن الله تعالى يقول يوم القيامة لآدم: قم فجهز من ذريتك تسع مائة وتسعة وتسعين إلى النار، وواحدا إلى الجنة فبكى أصحابه وبكوا ثم قال لهم رسول الله ﷺ: ارفعوا رؤوسكم، فوالذي نفسي بيده، ما أمتي في الأمم إلا كالشعرة البيضاء في جلد الثور الأسود فخفف ذلك عنهم.
Ahmad (27489) narrated it from Haytham, who said, Abu Rabi informed us, from Yunus, from Abu Idris, from Abu Darda, and he related it.Its chain of transmission is hasan because of Abu Rabi, as I established in al-Iman bil-Qadar. Haythami said in al-Majma (10/392), "Its chain of transmission is good."
