An absolutely beautiful excerpt from the final chapter of Mercy Oceans: Book 2, describing the Islamic perspective on the relationship between a husband and wife:
In Islam it is forbidden for a husband to look at strange women and for a wife to look at strange men. A man must look to his wife as the most sweet and beautiful. Harâm is not sweet, it is poison for you. A woman must look to her husband as the most sweet and handsome person, because she is not concerned with others. Her paradise is with her husband, and a man’s is with his wife. When Adam was in Paradise, walking alone, too much pressure was in his heart. He was not taking any pleasure until Allah created Eve, his wife. Then Paradise was full of pleasures; before that it was empty. Man without woman is incomplete, and woman without man is incomplete. No one can be proud over the other; they complete each other in this life and the life hereafter.
-Shaykh Mawlana Muhammad Nazim Adil al-Hakkani (qs)
