﴿وَيُطْعِمُونَ الطَّعَامَ عَلَىٰ حُبِّهِ مِسْكِينًا وَيَتِيمًا وَأَسِيرًا﴾
They give food, despite their love for it, to the poor, the orphan, and the captive. (al-Insān 76:8)
«وَيُطْعِمُونَ الطَّعَامَ» already states the charitable action. «عَلَىٰ حُبِّهِ» adds a meaningful circumstance. Giving food is commendable in itself; the qualification draws further attention to the donor's sacrifice, or to the religious motivation of the act under a different reading of the pronoun. Thus an added constituent deepens the moral significance of an otherwise complete report.
