What is wafq in Islam? Is it permissible to practise it or have it practised? The short answer is…
Meaning harmony in Turkish, wafq is a shape formed by dividing a rectangle into parts and writing some numbers and letters in the divisions and those who practice this claim that Allah will assign a jinn to protect them by means of wafq.
The religion of Islam strictly prohibits fortune-telling, amulet, and magic as they are against the belief of tawhid. (al-Fatawa al-Hindiyya, V, 459).
Magics and amulets which means to ask help from jinns and demons and whose meaning cannot be understood are practices that may lead one to assigning partner to Allah (Nawawi, al-Majmu’, IX, 66). Because there is always deception, evil and harm in such practices. (Jassas, Ahkam al-Qur’an, I, 61)
