The word(s) "contribution" appears 4 time(s) in 3 verse(s) in Quran in Muhammad Pickthal translation.

(1) Verily Allah heard the saying of those who said, (when asked for contributions to the war): "Allah, forsooth, is poor, and we are rich!" We shall record their saying with their slaying of the prophets wrongfully and We shall say: Taste ye the punishment of burning!

(2) Say: Pay (your contribution), willingly or unwillingly, it will not be accepted from you. Lo! ye were ever froward folk.

(3) And naught preventeth that their contributions should be accepted from them save that they have disbelieved in Allah and in His messenger, and they come not to worship save as idlers, and pay not (their contribution) save reluctantly.
