How do I answer someone who asks where Allah is?
You should say that He is over His Throne, as Allah (Exalted be He) says:
The Most Gracious (Allâh) rose over (Istawâ) the (Mighty) Throne (in a manner that suits His Majesty).
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
