وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ
أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «وُكِّلَ بِهِ سَبْعُونَ مَلَكًا» يَعْنِي الرُّكْنَ الْيَمَانِيَ «فَمَنْ قَالَ: اللَّهُمَّ إِنِّي أَسْأَلُكَ الْعَفْوَ وَالْعَافِيَةَ فِي الدُّنْيَا وَالْآخِرَةِ رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الْآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ قَالُوا: آمين»
The Prophet (sallallahu alayhi wa sallam) said:, “Seventy angels have been put in charge of it (i.e. the Yamani corner), so if anyone says, ‘O God, I ask Thee for pardon and wellbeing in this world and the next; our Lord, bring us a blessing in this world and a blessing in the next, and guard us from the punishment of hell’, they will say Amen.”
