Translation of the verse 37 from Surah Al-Waqi‘ah : Number of verses 96 - - page 535 - Part 27.
Loving (their husbands only), equal in age.
Devoted [to their husbands] and of equal age,
(56:37) intensely loving *18 and of matching age. *19
*18) The word 'uruban is used for the best feminine qualities of the woman in Arabic. This signifies a woman who is graceful and elegant, well-mannered and eloquent, and brimful of feminine feelings, who loves her husband with all her heart, and whose husband also loves her with all his heart.
*19) This can have two meanings: (1) That they will be of equal age with their husbands; and (2) that they will be of equal age among themselves; i.e. all the women in Paradise will be of the same age and will eternally stay young. Both these meanings may be correct at one and the same time, i.e. these women may be of equal age among themselves and their husbands also may be made of equal age with them. .According to a ,Hadith, "When the dwellers of Paradise enter it, their bodies will be without hair, their moustaches will be just appearing, but will yet he beardless, they will be handsome and fair-complexioned, with sturdy bodies and collyrium- stained eyes; they will all be 33 years of age." (Musnad Ahmad: Marwiyat Abi Hurairah). Almost the same theme has been related in Tirmidhi by Hadrat Mu'adh bin Jabal and Hadrat Abu Sa`id Khudri also.
