It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: The Prophet (peace and blessings be upon him) came to visit me (when I was ill) and said: "Shall I not perform over you the ruqyah that Jibril (peace be upon him) performed over me?" I said: "Of course! May my father and mother be sacrificed for you." He (peace and blessings be upon him) said: 'Bismillahi arqik, wallahu yashfik min kulli da'in fik, min sharri al-naffathati fi al-'uqad, wa min sharri hasidin idha hasad' (In the name of Allah I perform ruqyah over you, and Allah will cure you of every illness that is in you, from the evil of those who blow on knots, and from the evil of the envier when he envies). So he (peace and blessings be upon him) performed this ruqyah three times.
