Riyad as-Salihin 1429
Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) used to say in his prostration: Allahum-maghfir li dhanbi kullahu: diqqahu wa jillahu, wa 'awwalahu wa akhirahu, wa alaniyatahu wa sirrahu (O Allah! Forgive all my sins, the small and the great, first and the last, the open and the secret)." [Muslim] .
وعنه أن رسول الله صلى الله عليه وسلم كان يقول في سجوده‏:‏ “اللهم اغفر لي ذنبي كله دقه وجله، وأوله وآخره، وعلانيته وسره‏"‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏
