Q: What is your Eminence’s opinion on the name “Razzaq” and “Um Razzaq”? 
A: It is not permissible to use this name since Al-Razzaq (The All- Provider) is Allah (Glorified and Exalted be He):
Verily, Allâh is the All-Provider, Owner of Power, the Most Strong. 
Accordingly, the name Abdul-Razzaq is the one to be used. Also, it is not permissible to say Um (the mother of) Razzaq or Um Khallaq (The Creator), for both Names are Attributes of Allah (Glorified and Exalted be He). Rather, this woman should say Um Abdul-Razzaq instead and if she has an ID card, she should change it if she is able to.
 Question no. 9, tape no. 232.
