It was narrated that Al-Musayyab bin Rafi' said: I heard Al-Bara' bin 'Azib say: The Messenger of Allah said: 'whoever follows a Janazah until the prayer is offered, he will haveone Qirat of reward and whoever walks with the funeral until (the body) is buried will have two Qirats of reward, and a Qirat is like Uhud. '
It was narrated that 'Abdullah bin Al-Mughaffal said: The Messenger of Allah said: 'Whoever follows a Janazah until it is finished, he will have two Qirats, and whoever goes back before it is finished, he will have one Qirat.
