´"Abu Sa'eed narrated:` "The Messenger of Allah (s.a.w) dispatched us on a military expedition. We camped with some people and asked them to entertain us but they did not entertain us. Their leader was stung so they came to us saying: 'Is there anyone among you who can treat a scorpion sting with Ruqyah?' I said: 'Yes I can. But I will not do any Ruqyah until you give us some sheep.' They said: 'Then we shall give you thirty sheep.' We accepted that,and I recited Al-Hamda [Lillah] seven times. He became better and we took the sheep." He said: "We became concerned about that being permissible and said: 'Do not be hasty until we reach the Messenger of Allah (S.A.W)." He said: "When we arrived with him I mentioned what I did to him. He(S.A.W)said: 'How did you know that it was a Ruqyah? Take the sheep, and assign me a share among you.'"

´"Abu Sa'eed Al Khudri narrated:` "Some of the Companions of the Messenger of Allah (S.A.W) came across a tribe of Bedouins that did not entertain them,nor behave hospitality with them. Their leader became ill, and they came to us saying: 'Do you have any medicine?'We said: ' Yes. But you did not entertain us nor have us as guests so we will not do anything until you give us something.' Then they gave sheep for that." He said: 'So a man from us began reciting the Opening of the Book (Surat Al-Fatihah) and he was cured. So when we came to the Messenger of Allah (S.A.W) we mentioned to him, He said: 'How did you know it was Ruqyah?' And he did not mention any prohibition against it,and he said: 'Eat , and assign me a share among you from them (Sheep).'"
