Dua number 65

اَللّٰهُمَّ مَغْفِرَتُكَ اَوْسَعُ مِنْ ذُنُوْبِي

allaahumma maghferatoka awsa-o’ min zonoobee

O Allah! Your forgiveness is greater than my sinsْ

In al-Behaar: Narrated from Abdillah ibn Sinan from Abi Abdillah (a.s.):
When the Holy Prophet (s.a.w.a.) put his face (on the earth) for sujood, he (s.a.w.a.) would say

وَ رَحْمَتُكَ اَرْجٰي عِنْدِيْ مِنْ عَمَلِيْ

wa rahmatoka arjaa i’ndee min a’malee

and I am more hopeful of Your mercy than of my actions,

 

فَاغْفِرْ لِيْ ذُنُوْبِيْ يَا حَيًّا لَا يَمُوْتُ.

faghfir lee zonoobee yaa hayyan laa yamooto.

so forgive my sins; O Living! Who never dies!
