What is the method for nullifying sorcery or a spell that is suspected to have been cast in a clothing store, causing a halt in business and a cessation of customers? Are there specific Quranic verses to be recited over water and then sprinkled in the place to nullify sorcery, and if so, what are they?

The entire Holy Quran is a healing. It has been reported that the Prophet, peace and blessings be upon him, used to perform ruqyah (exorcism) with the Mu'awwidhat (Surahs of refuge), such as "Qul Huwa Allahu Ahad" (Surah Al-Ikhlas) and the two Mu'awwidhat (Surah Al-Falaq and Surah An-Nas). He would blow on himself with them when he felt unwell. It is also authentically reported that the Prophet, peace and blessings be upon him, specifically designated Al-Fatihah for ruqyah. Ibn Al-Qayyim also mentioned reciting specific verses from the Quran into water and pouring it over the head of one afflicted by magic. Sheikh Ibn Baz commented on a Hadith from Abu Dawud about the Prophet, peace and blessings be upon him, reciting into water and pouring it over a sick person, stating that treating by reciting into water and pouring it over the sick is not religiously forbidden if the recitation is sound. In conclusion, ruqyah for magic and the evil eye is authentically established from the Prophet, peace and blessings be upon him. One can recite Al-Fatihah, Al-Ikhlas, and the two Mu'awwidhat into water and blow into it, or recite the aforementioned verses or others and sprinkle the place with it.
