Charity from members, we hear (4)
I believe the answer is:
'charity' is the definition.
(alms is a kind of charity)
'members we hear' is the wordplay.
'members' becomes 'arms' (arm is a kind of member).
'we hear' indicates a 'sounds like' (homophone) clue.
'arms' sounds like 'ALMS'.
'from' acts as a link.
(Other definitions for alms that I've seen before include "Money given to poor people" , "Charitable giving" , "Old word for money given to the poor" , "Charity for poor" , "Relief for the poor" .)
