أن رسول الله صلى الله عليه وسلم كان يقول في سجوده: «اللهم اغفر لي ذنبي كله دقه وجله، وأوله وآخره، وعلانيته وسره
The Messenger of Allah (sallallahu alayhi wa sallam) 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).’.
