عُرُ‌بًا (...amorous to their husbands,...56:37). The word ` urub, is the plural of ` arubah. This refers to a woman who loves her husband passionately and is his beloved.

أَتْرَ‌ابً (...matching them in age...56:37) The word atrab is the plural of tirb, meaning 'a person of equal age who played together with his mate in dust'. The verse means that men and women will be made of equal ages in Paradise. Some narrations report that they will be about thirty-three years old. [ Mazhari ]
