وعن جابر رضي الله عنه
قال: كنا مع النبي صلى الله عليه وسلم في غزاة فقال: «إن بالمدينة لرجالا ما سرتم مسيرًا، ولا قطعتم واديًا إلا كانوا معكم حبسهم المرض»
We accompanied the Prophet (sallallahu alayhi wa sallam) in an expedition when he (sallallahu alayhi wa sallam) said, “Some people have remained behind us in Al-Madinah, and we never cross a valley but they are with us. They share the reward with us because they have been held back by valid excuse.”In another narration the wordings are: “…by any genuine excuse.”In another narration the wordings are: “They are your partners in reward.”.
