Surah 76. Al-Insan, Ayah 8

The term asir denotes anyone who is a "captive" either literally (e.g., a prisoner) or figuratively, i.e., a captive of circumstances which render him helpless; thus, the Prophet said, "Thy debtor is thy captive; be, therefore, truly kind to thy captive" (Zamakhshari, Razi, et al.). The injunction of kindness towards all who are in need of help - and therefore "captive" in one sense or another - applies to believers and non-believers alike (Tabari, Zamakhshari), and apparently also to animals dependent on man.

Or, as in 2:177 , "however much they themselves may cherish [i.e., "need"] it"; cf. also {90:14-16}. It is to be noted that in this context the concept of "giving food" comprises every kind of help and care, both material and moral.

The captive: when taken literally, it refers to the old state of things when captives of war had to earn their own food, or their own redemption; even ordinary prisoners in jail for criminal offences often starved unless food was provided for them by private friends or from their own earnings.
