عن أبي عبيدة بن عبد الله عن أبيه قال: قال رسول الله صلى الله عليه وسلم: التائب من الذنب كمن لا ذنب له (سنن ابن ماجة رقم 4250)

Hazrat Abu ‘Ubaidah (rahimahullah) reports from his father, Hazrat ‘Abdullah bin Mas’ood (radhiyallahu ‘anhu), that Rasulullah (sallallahu ‘alaihi wasallam) said, “The person who sincerely repents from a sin (and reforms his life) is like a person who has not committed the sin.”
