A:The use of a Ta’weez is permissible as long as the person has the correct belief; that the Ta’weez can have no effect except with the permission of Allah Ta’aala and the actual doer is Allah.
It is recorded in Mirqaat that the Sahaabah (Radhiyallaahu Anhum) placed Ta’weez on their children and Rasulullah (Sallallaahu Alayhi wa Sallam did not forbid them from doing so.
In Muslim it is mentioned that Rasulullah (Sallallaahu Alayhi wa Sallam) checked the Ta’weez of the Sahaabah and approved of it on condition that there is no Shirk in it.
Bukhari and Muslim records that Sayyidina Anas (Radhiyallaahu Anhu) said that Rasulullah (Sallallaahu Alayhi wa Sallam) gave permission for Ta’weez for Nazar (evil eye) and fever.
Ta’weez is permissible on condition that the wordings are correct and it is free from any type of Shirk and Kufr.
Allah Ta’aala knows best.
