Chapter 97: Oneness, Uniqueness of Allah (Tawheed)
Narrated 'Abdullah bin 'Amr: Abu Bakr As-Siddiq said to the Prophet (ﷺ) "O Allah' s Messenger (ﷺ)! Teach me an invocation with which I
may invoke Allah in my prayers." The Prophet (ﷺ) said, "Say: O Allah! I have wronged my soul very
much (oppressed myself), and none forgives the sins but You; so please bestow Your Forgiveness
upon me. No doubt, You are the Oft-Forgiving, Most Merciful."
