Answered by our Shaykh, the ‘Allaamah, the Sincere Adviser, Abu ‘Abdirrahman Yahya bin ‘Ali Al-Hajoori – may Allaah preserve him – on the 28th, Saffar, 1441H
What’s the ruling of naming with the name ‘Abdud-Dayyaan?
There’s nothing preventing this, and the proof is the hadith:
“أنا الملك أنا الديان”
“I am the King, I am the Judge.”
Translated by Abu ‘Abdillah ‘Umar bin Yahya Al-‘Akawi
