Silsilah as-Sahihah 80 — Reward for good deeds is ten to seven hundred

Sayyiduna Abu Dharr (may Allah be pleased with him) says: The Truthful and Trusted (Muhammad, peace and blessings be upon him) narrated to us from his Lord that Allah Almighty said: "I reward a good deed tenfold or even more, and I recompense an evil deed only onefold or I may even forgive it. (O My servant!) If you come to Me with sins nearly as much as the earth, I will grant you forgiveness just as great, provided that you did not associate anyone with Me."
