Ruh bin Zinba’ says: I went to Sayyiduna Tamim Dari (may Allah be pleased with him), at that time he was the governor of Bayt al-Maqdis and he was removing the husks from barley and straw for his horse. I said: O Amir! Could you not find someone to do this work for you? He replied: I heard the Messenger of Allah (peace and blessings be upon him) say:“Whoever cleans barley for his horse in the way of Allah, then prepares it and hangs it with the horse, Allah Almighty writes for him a good deed for every grain of barley.”
