Narrated from Sahl bin Sa’d (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said:“Guarding the frontier for one day in the way of Allah is better than the world and all that is in it. A place in Paradise as small as the whip of one of you is better than the world and all that is in it, and a servant’s going forth in the morning or evening in the way of Allah is better than the world and all that is in it.”
