Ruqyah is a multi-purpose prayer that can shield us from all types of magic spells, evil eye, sorcery and different types of witchcraft and haunting by the evil spirits.
The most excellent and suggested way is that a Muslim should do it for himself/herself or for his/her loved ones. Our dear Prophet Muhammad (saw) used to do it for himself. Narrated Hazrat Aisha (RA) “When the Messenger of Allah (saw) was sick he used to recite Al-Mu’awidhatayn, i.e. Surah Al-Falaq and An-Nas over him body and spit dryly. If his pain aggravated then I used to recite Al-Mu’awidhatayn over him and wiped him with his own hand to seek its blessing.” (Al-Bukhari).
As far as giving something to the Raqi (a person who performs Ruqyah) is concerned there is a hadith that proves in a subtle way that this practice is not forbidden in Islam. Narrated on the authority of Abu Saeid Al-Khudry (may Allah be pleased with him), he said, Abu Sa'id Khudri reported that some of the Companions of Allah's Messenger (peace be upon him) set out on a journey and they happened to pass by an Arabian tribe. They demand for hospitality from the tribe was turned down. After some time the members of the tribe came and asked the Sahaaba, ‘Is there any incantator amongst you, at the chief of the tribe has been stung by a scorpion? One of the Sahaaba replied, ‘Yes. So he came to him and he performed ruqyah with the help of Sura al-Fatiha and the chief of the tribe got cured. He was rewarded a flock of sheep but the Sahaaba refused to accept it, saying, ‘I shall mention about this to Allah's Apostle (may peace be upon him). If he approves of it only then I shall accept the reward. So we came to Prophet Mohammad (saw) and narrated the incident to him saying that, ‘Oh Allah's Messenger! By Allah, I practiced ruqyah only with the help of Sura al-Fatiha from the Holy Quran. Prophet Mohammad (saw) smiled and asked, ‘How did you come to know that it can be used as ruqyah? Take out of that and allocate a share for me along with your share’.
From this Hadith we get to know that it is permissible to give something in return to the person who performs it. We also learn from it that Surah Al-Fatiha can be used for curing evil eye and other such diseases.
