"He said: I heard the Messenger of Allah (blessings and peace of Allah be upon him) say: 'There will come to you Uways ibn ‘Aamir with the reinforcements from Yemen, from Muraad then from Qaran. He had leprosy but he recovered from it except for a spot the size of a dirham. He has a mother and he honours her. If he were to swear in the name of Allah that something should happen, Allah would cause it to happen. If you can ask him to pray for forgiveness for you then do so."
