Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) says: I heard the Prophet (peace and blessings be upon him) say: "Setting out in the morning or in the evening in the path of Allah is better than the world and everything in it, and a place in Paradise the size of one of your whips is better than the world and everything in it."
