quran:36:36 –

Exalted is He who created all pairs - from what the earth grows and from themselves and from that which they do not know.  

Glory be to Him Who created all the pairs, the specimens, of what the earth produces, of seeds and other things, and of themselves, of males and females, and of what they do not know, of marvellous and strange creatures.
القرآن:٣٦:٣٦ –

سُبْحَانَ الَّذِي خَلَقَ الْأَزْوَاجَ كُلَّهَا مِمَّا تُنْبِتُ الْأَرْضُ وَمِنْ أَنْفُسِهِمْ وَمِمَّا لَا يَعْلَمُونَ  

{سبحان الذي خلق الأزواج} الأصناف {كلها مما تنبت الأرض} من الحبوب وغيرها {ومن أنفسهم} من الذكور والإناث {ومما لا يعلمون} من المخلوقات العجيبة الغريبة.
