He remained going around the tent until the morning, and when the Prophet got up and saw him in his place, he asked him: "What is up with you, O Abu Ayyoob?" He replied, “O Messenger of Allah, I was afraid of this woman (i.e., Safiyyah) on you, for you have just killed her father, her husband and her people, and until recently, she was in unbelief. So I was afraid of her on you." Whereupon, the Prophet said: "O Allah! Preserve Abu Ayyoob as he spent the night preserving me."
