۞ 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 189

It is He who created you from one soul and created from it its mate that he might dwell in security with her. And when he [i.e., man] covers her, she carries a light burden [i.e., a pregnancy] and continues therein. And when it becomes heavy, they both invoke Allāh, their Lord, "If You should give us a good [child], we will surely be among the grateful."
