Al-A'raf - 7:189

هُوَ الَّذِي خَلَقَكُم مِّن نَّفْسٍ وَاحِدَةٍ وَجَعَلَ مِنْهَا زَوْجَهَا لِيَسْكُنَ إِلَيْهَا فَلَمَّا تَغَشَّاهَا حَمَلَتْ حَمْلاً خَفِيفًا فَمَرَّتْ بِهِ فَلَمَّا أَثْقَلَت دَّعَوَا اللّهَ رَبَّهُمَا لَئِنْ آتَيْتَنَا صَالِحاً لَّنَكُونَنَّ مِنَ الشَّاكِرِينَ
[7:189]
He it is Who created you from a single being, and of the same (kind) did He make his mate, that he might incline to her; so when he covers her she bears a light burden, then moves about with it; but when it grows heavy, they both call upon Allah, their Lord: If Thou givest us a good one, we shall certainly be of the grateful ones.
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."
He it is Who did create you from a single soul, and therefrom did make his mate that he might take rest in her. And when he covered her she bore a light burden, and she passed (unnoticed) with it, but when it became heavy they cried unto Allah, their Lord, saying: If thou givest unto us aright we shall be of the thankful.
