How is recitation performed in treatment with the Qur'an?

Question:
Regarding treatment with the Qur'an: Should one increase the recitation for the afflicted person by reciting many surahs, or is one surah sufficient?

Answer:
Whatever is easy, but if one recites *Qul Huwa Allahu Ahad* and the two *Mu'awwidhat*, that is better. This is because when the Prophet (peace and blessings be upon him) was afflicted with sorcery, Allah cured him of the evil that had befallen him. He said: , meaning and , along with . The Prophet (peace and blessings be upon him) used to recite them three times in the morning and three times in the evening when going to sleep. The Companions used to treat those bitten by scorpions with *Surat al-Fatihah*, and Allah cured them in that manner.
Q: May Allah reward you. If one is certain that it will cure...
The Shaykh: The point is that one should recite whatever is easy. The entire Qur'an is a cure.
Q: ... They say that if it does not have an effect on the person during the recitation, it is considered that the cure is not certain.
The Shaykh: No, it is not necessary. However, some people may recite without having certainty, without having a good intention, and their recitation does not benefit. And some people—the one being recited to—do not have trust in the reciter, nor trust in the Qur'an, nor trust in Allah; so the recitation does not benefit them. But if Allah brings them together: the reciter is trustworthy and believes in Allah, and that Allah is the disposer of affairs, and the one being recited to has trust in Allah and faith in Allah; then, by the permission of Allah, the cure will occur.
