وَ قَدْ رُوِيَ عَنْ أَبِي بَكْرِ بْنِ أَبِي سَمَّالٍ قَالَ: صَلَّيْتُ خَلْفَ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ اَلْفَجْرَ فَلَمَّا فَرَغَ مِنْ قِرَاءَتِهِ فِي اَلثَّانِيَةِ جَهَرَ بِصَوْتِهِ نَحْواً مِمَّا كَانَ يَقْرَأُ وَقَالَ « اَللَّهُمَّ اِغْفِرْ لَنَا وَ اِرْحَمْنَا وَ عَافِنَا وَ اُعْفُ عَنَّا فِي اَلدُّنْيَا وَ اَلْآخِرَةِ «إِنَّكَ عَلىٰ كُلِّ شَيْءٍ قَدِيرٌ ».
Abu Bakr ibn Abi Samal who said: "I prayed behind Abu Abdullah (a.s) for Fajr (dawn prayer). When he finished the recitation in the second rak'ah, he raised his voice slightly as if reciting and said: Allahumma ighfir lana wa irhamna wa ‘afina wa ‘u‘fu ‘anna fi ad-dunya wa al-akhirah. Innaka ‘ala kulli shay’in qadeer 'O’ Allah (swt), forgive us, have mercy on us, grant us well-being, and pardon us in this world and the Hereafter. Truly, You have power over all things.'".
