Verse 189

هُوَ ٱلَّذِى خَلَقَكُم مِّن نَّفْسٍ وَٰحِدَةٍ وَجَعَلَ مِنْهَا زَوْجَهَا لِيَسْكُنَ إِلَيْهَا فَلَمَّا تَغَشَّىٰهَا حَمَلَتْ حَمْلًا خَفِيفًا فَمَرَّتْ بِهِۦ فَلَمَّآ أَثْقَلَت دَّعَوَا ٱللَّهَ رَبَّهُمَا لَئِنْ ءَاتَيْتَنَا صَـٰلِحًا لَّنَكُونَنَّ مِنَ ٱلشَّـٰكِرِينَ

He is the One who created you from a single soul and made from her, her mate in order to achieve tranquility with her. Then once the conception occurred, she carries a small load that hardly can be noticed. Then when it becomes heavier, they implore God, the Lord of both, if you only grant us a righteous one, we will indeed be grateful.
