Word of sympathy received by prophet, understood (8)
I believe the answer is:
gathered
'understood' is the definition.
('gather' can be a synonym of 'understand')
'word of sympathy received by prophet' is the wordplay.
I cannot quite see how this works, but
'word' could be 'there' (I have seen 'comforting word' mean 'there' so perhaps 'word' could also mean 'there') and 'there' is found in the answer.
The remaining letters 'gad' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for gathered that I've seen before include "The grade (anag.)" , "Concluded from evidence" , "Accumulated, brought together" , "Drew" , "Gleaned" .)
