Musannaf Ibn Abi Shaybah 37430 — The words of Abu Hurayrah

It is narrated from Abu Uthman that he said: It reached me from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: Allah Almighty rewards a believer for one good deed with one million good deeds. So I went to him and said: O Abu Hurayrah (may Allah be pleased with him), it has reached me from you that you say that Allah Almighty rewards a believer for one good deed with one million good deeds? He said: Yes, and with two million as well. In the noble Qur'an it says concerning this: "Indeed, Allah does not wrong anyone by even an atom's weight, and if it is a good deed, He multiplies it." So who knows the measure of those multiples? "And He gives from Himself a great reward" [Surah An-Nisa: 40]. He said: It is Paradise.
