Raising the hands in supplication

Jabir ibn 'Abdullah reported that at-Tufayl ibn 'Amr asked the Prophet, may Allah bless him and grant him peace, "Do you want a fortress and a citadel? The fortress of Daws." The Messenger of Allah, may Allah bless him and grant him peace, refused it because of what Allah had stored up for the Ansar. At-Tufayl made hijra and a man of his people made hijra with him. The man fell ill and was in torment (or words to that effect) and he crawled over to a quiver, took out an arrow, sliced his veins and died. At-Tufayl saw him a dream and asked him, "What has been done to you?" He replied, "I was forgiven because of my hijra to the Prophet, may Allah bless him and grant him peace." He asked, "What happened to your hands?" He replied, "It was said, 'We will not put right in you that part of your hands which you destroyed.'" He said that at-Tufayl related that tot he Prophet, may Allah bless him and grant him peace, and the Prophet said, "O Allah, forgive his hands!" and he raised his hands when he said it.
