What a muslim should say when he is praised
اَللّٰہُمَّ لَا تُؤَا خِذْنِيْ بِمَا یَقُوْلُوْنَ وَاغْفِرْلِيْ مَا لَا یَعْلَمُوْنَ [وَاجْعَلْنِيْ خَیْرًا مِّمَّا یَظُنُّوْنَ]
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].
