Hadith 2590
Abu Huraira reported the Prophet as saying, “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.” Ibn Majah transmitted it.
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 ". رَوَاهُ ابْن مَاجَه
