Dua 244 ☆
اللَّهُمَّ لاَ تُؤَاخِذْنِي بِمَا يَقُولُونَ، وَاغْفِرْ لِي مَا لاَ يَعْلَمُونَ، [وَاجْعَلْنِي خَيْراً مِمَّا يَظُّنُّونَ]
Allaahumma laa tu'aakhithnee bimaa yaqooloona, waghfir lee maa laa ya'lamoona [waj'alnee khayram-mimmaa yadhunnoon].
O Allah , do not call me to account for what they say and forgive me for what they have no knowledge of [and make me better than they imagine].
