Misguiding books

Q 3: We often hear about some books such as, Ibn Sina' (Avicenna), Abu Ma`shar Al-Falaky, Shumus Al-Anwar, and Al-Rahmah, and so on, do these books have an origin? Is believing in exorcizing Jinn, Al-`Aza'im (recitations of supplications over a sick person seeking healing), writing hirz (verses of guarding and refuge), and the like true? If it is true, is it permissible for a person to practice this as a profession and use these books to tell people that they will be sick on such and such day, at such and such time or if they come near water, at a certain time, when the wind blows, or when there is dew, and so on? If this is true, is it permissible for this person to use this book and practice this as a profession and take people's wealth unlawfully?

A: It is not permissible to act according to what is stated in these books which includes charlatanism and using Jinn. Moreover, it is not permissible to believe in whatever is stated in them as they include matters of Shirk (associating others with Allah in His Divinity or worship), Bid`ah (innovation in religion), superstitions, and false claims of knowing the Ghayb (Unseen). Knowledge of the Ghayb is attributed to Allah (Exalted be He) Alone and no one has knowledge of it except Him (Glorified be He). However, He might inform whoever He likes among His Messengers. It is better for you to avoid such books. (Part No. 12; Page No. 133) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
