هُوَ الَّذِي خَلَقَكُم مِّن نَّفْسٍ وَاحِدَةٍ وَجَعَلَ مِنْهَا زَوْجَهَا لِيَسْكُنَ إِلَيْهَا ۖ فَلَمَّا تَغَشَّاهَا حَمَلَتْ حَمْلًا خَفِيفًا فَمَرَّتْ بِهِ ۖ فَلَمَّا أَثْقَلَت دَّعَوَا اللَّهَ رَبَّهُمَا لَئِنْ آتَيْتَنَا صَالِحًا لَّنَكُونَنَّ مِنَ الشَّاكِرِينَ

It is He Who created you from a single person, and made his mate of like nature, in order that he might dwell with her (in love). When they are united, she bears a light burden and carries it about (unnoticed). When she grows heavy, they both pray to Allah their Lord, (saying): "If Thou givest us a goodly child, we vow we shall (ever) be grateful."
