Ali bin Abi Talib said: When the Prophet صلی اللہ علیہ وسلم uttered salutation at the end of the prayer, he used to say: O Allah, forgive me my former and latter sins, what I have kept secret and what I have done openly, and what I have done extravagance; and what You know better than I do. You are the Advancer, the Delayer, there is no god but You.
