"The Messenger of Allah(S.A.W) would seek refuge from the jinn and the (evil) eye of humans, until Al-Mu'awwidhatain were revealed. So when they were revealed he used them and left other than them."
" I said: 'O Messenger of Allah (S.A.W)! Some of Ja'far's children have suffered from an accelerated case of the inflammation of the eye, so should I have them treated with Ruqyah?' He said: 'Yes,for indeed if there was anything that could overcome the Decree, then the evil eye would overcome it."
""U'idhukuma bikalimatillahi-tammati,min kulli shaitanin wa hammatin, wa minkulli'ainin lammah (I seek refuge for the two of you in the Perfect Words of Allah, from every devil and every poisonous pest, and from every harmful eye)." And he would say: "It is with this that Ibrahim would seek refuge for Ishhaq and Ismail [peace be upon them]." Another chain reports a similar narration.
"If there was anything that could overcome the Decree then the (evil) eye would overcome it, and when you are requested to wash (due to it) then wash."
"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.'"
"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).'"
"I asked the Messenger of Allah (S.A.W): 'O Messenger of Allah(S.A.W)! Do you think that the Ruqyah we use, the treatments we use, and what we seek to protect ourselves will contradict anything from Allah's Decree?' He said: 'They are from Allah's Decree.'"
