Full Sharh — Musnad Ahmad 1155
حَدَّثَنَا يَحْيَى بْنُ آدَمَ، حَدَّثَنَا إِسْرَائِيلُ، عَنْ عَطَاءِ بْنِ السَّائِبِ، عَنْ أَبِي عَبْدِ الرَّحْمَنِ، قَالَ سَمِعْتُ عَلِيًّا، رَضِيَ اللَّهُ عَنْهُ يَقُولُ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ الْعَبْدَ إِذَا جَلَسَ فِي مُصَلَّاهُ بَعْدَ الصَّلَاةِ صَلَّتْ عَلَيْهِ الْمَلَائِكَةُ وَصَلَاتُهُمْ عَلَيْهِ اللَّهُمَّ اغْفِرْ لَهُ اللَّهُمَّ ارْحَمْهُ وَإِنْ جَلَسَ يَنْتَظِرُ الصَّلَاةَ صَلَّتْ عَلَيْهِ الْمَلَائِكَةُ وَصَلَاتُهُمْ عَلَيْهِ اللَّهُمَّ اغْفِرْ لَهُ اللَّهُمَّ ارْحَمْهُ.
English Translation
It was narrated that Abu `Abdur-Rahman said:: I heard ‘Ali (رضي الله عنه) say: The Messenger of Allah (ﷺ) said: “When a person sits in the place where he prayed after praying the angels send blessings upon him, and their blessings upon him are: O Allah, forgive him. O Allah have mercy on him. And if he sits waiting for the prayer, the angels send blessings upon him, and their blessings upon him are: O Allah, forgive him, O Allah have mercy on him.
