Reflection and remembrance (tathakkur)

سَيَقُولُونَ لِلَّهِ ۚ قُلْ أَفَلَا تَذَكَّرُونَ

They will say, "To Allāh." Say, "Then will you not remember?"

وَمِن كُلِّ شَىْءٍ خَلَقْنَا زَوْجَيْنِ لَعَلَّكُمْ تَذَكَّرُونَ

And of all things We created two mates [i.e., counterparts]; perhaps you will remember.
