۞ هُوَ ٱلَّذِى خَلَقَكُم مِّن نَّفْسٍۢ وَٰحِدَةٍۢ وَجَعَلَ مِنْهَا زَوْجَهَا لِيَسْكُنَ إِلَيْهَا ۖ فَلَمَّا تَغَشَّىٰهَا حَمَلَتْ حَمْلًا خَفِيفًۭا فَمَرَّتْ بِهِۦ ۖ فَلَمَّآ أَثْقَلَت دَّعَوَا ٱللَّهَ رَبَّهُمَا لَئِنْ ءَاتَيْتَنَا صَٰلِحًۭا لَّنَكُونَنَّ مِنَ ٱلشَّٰكِرِينَ
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.
Surah Al-A'raaf(7:189)
