وعن فضالة بن عبيد رضي الله عنه
أن رسول الله صلى الله عليه وسلم قال: «كل ميت يختم على عمله إلا المرابط في سبيل الله فإنه ينمى له عمله إلى يوم القيامة، ويؤمن فتنة القبر»
The Messenger of Allah (sallallahu alayhi wa sallam) said, “The actions of every dead person come to a halt with his death except the one who is on the frontier in Allah’s way (i.e., observing Ribat). This latter’s deeds will be made to go on increasing for him till the Day of Resurrection, and he will be secure from the trials in the grave.”.
