'Abdullah said, "The Prophet, may Allah bless him and grant him peace, swore an oath like one of the oaths that people swear and a man of the Ansar said, 'By Allah, it is not an oath by which the Face of Allah Almighty is desired." I said, 'I will tell the Prophet, may Allah bless him and grant him peace. I went to him while he was with his Companions and I spoke to him in confidence. It clearly affected him greatly, may Allah bless him and grant him peace, and his face changed colour so that I wished that I had not told him. Then he said, 'Musa was injured with greater than that and he endured it.'"
