The Consideration of Hazrat ‘Uthmaan (radhiyallahu ‘anhu) towards his Servants
‘Abdullah Roomi (rahimahullah) mentions that when Hazrat ‘Uthmaan (radhiyallahu ‘anhu) would perform wudhu during the night, he would not take assistance from anyone (in pouring the water over his limbs). When someone suggested to him that he appoint one of the servants to assist him and pour the water for him, he said, “No! I do not wish to take service from them at night as the night is the time for them to rest.”
