A man will come to you who is called Uweis. He had a condition of whiteness [leprosy], so he made supplications to Allah, and Allah cured it. So, whoever among you meets him, ask him to supplicate for Allah's forgiveness for you. So, 'Umar met him and said: Supplicate for Allah's forgiveness for me. So Uweis supplicated for Allah's forgiveness for him.
