Hisnul Muslim 46

While sujood

اللَّهُمَّ اغْفِرْ لِي ذَنْبِي كُلَّهُ، دِقَّهُ وَجِلَّهُ، وَأَوَّلَهُ وَآخِرَهُ وَعَلَانِيَتَهُ وَسِرَّهُ

Allaahum-maghfir lee thanbee kullahu, diqqahu wa jillahu, wa 'awwalahu wa 'aakhirahu wa 'alaaniyata hu wa sirrahu.

O Allah, forgive me all my sins, great and small, the first and the last, those that are apparent and those that are hidden.
