Allah's Wisdom in Creation

وَلَوْ شَآءَ رَبُّكَ لَجَعَلَ ٱلنَّاسَ أُمَّةً وَٰحِدَةً ۖ وَلَا يَزَالُونَ مُخْتَلِفِينَ

And if your Lord had willed, He could have made mankind one community; but they will not cease to differ,

لِّلَّهِ مُلْكُ ٱلسَّمَـٰوَٰتِ وَٱلْأَرْضِ ۚ يَخْلُقُ مَا يَشَآءُ ۚ يَهَبُ لِمَن يَشَآءُ إِنَـٰثًا وَيَهَبُ لِمَن يَشَآءُ ٱلذُّكُورَ

To Allāh belongs the dominion of the heavens and the earth; He creates what He wills. He gives to whom He wills female [children], and He gives to whom He wills males.

فَقَدَرْنَا فَنِعْمَ ٱلْقَـٰدِرُونَ

And We determined [it], and excellent [are We] to determine.
