Narrated by:Abu Hurairah that the Messenger of Allah said
It was narrated from Abu Hurairah that the Messenger of Allah said:"Whoever follows the funeral of a Muslim man, seeking reward, and offers the prayer and buries him, will have two Qirats. And whoever offers the funeral prayer then goes back before the burial, then he returns with one Qirat of reward."
أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، عَنْ عَوْفٍ، عَنْ مُحَمَّدِ بْنِ سِيرِينَ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ تَبِعَ جَنَازَةَ رَجُلٍ مُسْلِمٍ احْتِسَابًا فَصَلَّى عَلَيْهَا وَدَفَنَهَا فَلَهُ قِيرَاطَانِ وَمَنْ صَلَّى عَلَيْهَا ثُمَّ رَجَعَ قَبْلَ أَنْ تُدْفَنَ فَإِنَّهُ يَرْجِعُ بِقِيرَاطٍ مِنَ الأَجْرِ " .
