Arabic (Original)
حَدَّثَنَا عَبْد اللَّهِ حَدَّثَنِي قَالَ قَرَأْتُ عَلَى عَبْدِ الرَّحْمَنِ : مَالِكٌ عَنْ أَبِي الزِّنَادِ عَنِ الْأَعْرَجِ عَنْ أَبِي هُرَيْرَةَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الْمَلَائِكَةُ تُصَلِّي عَلَى أَحَدِكُمْ مَا دَامَ فِي مُصَلَّاهُ تَقُولُ اللَّهُمَّ اغْفِرْ لَهُ اللَّهُمَّ ارْحَمْهُ.
English Translation
'Abdullah told me: He said: I read to 'Abd al-Rahman: Malik, from Abu al-Zinad, from al-A'raj, from Abu Hurayrah, that the Messenger of Allah, peace and blessings be upon him, said: "The angels continue to pray for one of you as long as he remains in his place of prayer, saying: 'O Allah, forgive him; O Allah, have mercy on him.'"
