How uncomfortable a couch to recline on! 29 Indeed, those who have believed and done righteous deeds - indeed, We will not allow to be lost the reward of any who did well in deeds. 30 Those will have gardens of perpetual residence; beneath them rivers will flow. They will be adorned therein with bracelets of gold and will wear green garments of fine silk and brocade, reclining therein on adorned couches. Excellent is the reward, and good is the resting place. 31
