It was narrated that ‘Asim bin ‘Ubaidullah said:
“I heard ‘Abdullah bin ‘Amir bin Rabi’ah narrating from his father that the Prophet (ﷺ) said: “There is no Muslim who sends peace and blessings upon me, but the angels will send peace and blessings upon him as long as he sends peace and blessings upon me. So let a person do a little of that or a lot.”
حَدَّثَنَا بَكْرُ بْنُ خَلَفٍ أَبُو بِشْرٍ، حَدَّثَنَا خَالِدُ بْنُ الْحَارِثِ، عَنْ شُعْبَةَ، عَنْ عَاصِمِ بْنِ عُبَيْدِ اللَّهِ، قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ عَامِرِ بْنِ رَبِيعَةَ، عَنْ أَبِيهِ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَ ‏ "‏ مَا مِنْ مُسْلِمٍ يُصَلِّي عَلَىَّ إِلاَّ صَلَّتْ عَلَيْهِ الْمَلاَئِكَةُ مَا صَلَّى عَلَىَّ فَلْيُقِلَّ الْعَبْدُ مِنْ ذَلِكَ أَوْ لِيُكْثِرْ ‏"‏ ‏.‏
