Whom some call a heavenly being (5)

I believe the answer is:

allah

I'm a little stuck... Click here to teach me more about this clue!

'whom' is the definition.
I can't tell whether this defines the answer.

'some call a heavenly being' is the wordplay.
'some' indicates a hidden word (some parts of the word are used).
'ALLAH' is hidden in the letters of 'call a heavenly being'.

Can you help me to learn more?

(Other definitions for allah that I've seen before include "Divinity" , "God of the Arabs" , "God in Islam" , "God of the Muslims" , "God worshipped in 5 Across" .)

I've seen this clue in The Globe and Mail.
