Hazrat Ali (may Allah be pleased with him) says that whenever I heard a hadith from the Prophet (peace and blessings be upon him), Allah granted me some benefit from it. And if someone else narrated it to me, I would make him swear an oath to its truthfulness. If he swore, I would accept it as true. And Hazrat Abu Bakr truthfully narrated to me that the Messenger of Allah (peace and blessings be upon him) said: Whenever a servant commits a sin, then performs ablution well, then offers two rak‘ahs or any prayer, and seeks forgiveness from Allah, Allah forgives him.
