Abu Musabbih narrates from Awza'i, he says: We were walking on the open road entering the Qalamiyah region of the land of Rome, when Malik bin Abdullah Khath'ami, who was the leader, called out to a man who was walking at the foot of the mountain. The leader said: O Abu Abdullah! Will you not ride? For I heard the Messenger of Allah, peace and blessings be upon him, say: Whoever's two feet become dusty in the way of Allah for some part of the day, Allah will make the Fire forbidden for him.
