Surah Al Layl Tafseer

By Him Who created male and female.

This is similar to Allah's saying,

وَخَلَقْنَـكُمْ أَزْوَجاً

And We have created you in pairs. (78:8)

It is also similar to saying,

وَمِن كُلِّ شَىْءٍ خَلَقْنَا زَوْجَيْنِ

And of everything We have created pairs. (51:49)

And just as these things that are being sworn by are opposites, likewise that which this swearing is about are opposing things.

This is why Allah says,

إِنَّ سَعْيَكُمْ لَشَتَّى
