«كل عمل منقطع عن صاحبه إذا مات إلا المرابط في سبيل الله فإنه ينمى له عمله ويجرى عليه رزقه إلى يوم القيامة»
The Prophet (peace and blessings be upon him) said:
"After a man dies, every deed of his is cut off, except the one who guards the frontier in the path of Allah; his deeds keep increasing for him until the Day of Resurrection and he continues to receive provision."
