Hakim al Umma Maulana Ashraf Ali Thanwi (Allah have mercy on him) said,
‘I received a letter from a female. She has has written few complaints of her husband. She further wrote that if I forbid him from indulgence in wrongful acts he rebukes me excessively. She requested an amulet (ta’weez) or a recitation (wazifa) for his reform (islah).
I wrote to her in reply that if there is no fear of retaliation (to your advice) then you can do so with extreme politeness and flattery. Otherwise, you are excused. Do not say anything (to him in this regards).
(Hakim al Umma then addressed the seekers beside him) Is islah possible by amulets (ta’weez) or recitations (wazifa)?
It is difficult to reform an individual who himself does not want to improve.’
