تفسير : (requital) a reward (from thy lord a gift) that he bestows upon them in the garden (in payment) ten rewards for each good deed; and it is also said this means: reward in proportion to their good deeds
Jalāl al-Dīn al-Maḥallī
تفسير : [this will be] a reward from your lord, in other words, god has rewarded them with this reward as, a gift (‘atā’an substitutes for jazā’an, ‘reward’) that is sufficing, [that is] abundant (hisāban, [as meaning ‘abundant’] derives from their saying a‘tānī fa-ahsabanī, ‘he gave me so abundantly that i said, “that is enough for me”’ [hasbī]),
