“Have you seen the one who denies the Recompense? That is the one who repulses the orphan and does not urge the feeding of the poor.”
Ibn Kathir observes that the surah defines the denier of the Judgement by two social sins before it mentions worship at all: harshness to the orphan, who cannot repay, and failing even to encourage others to feed the hungry. Al-Razi notes the phrase is not that he fails to feed the poor himself but that he does not urge it, a still lower bar, so that indifference to the plight of others is itself a mark of the hard heart.
