The Quran

أَوَلَم يَتَفَكَّروا في أَنفُسِهِم ۗ ما خَلَقَ اللَّهُ السَّماواتِ وَالأَرضَ وَما بَينَهُما إِلّا بِالحَقِّ وَأَجَلٍ مُسَمًّى ۗ وَإِنَّ كَثيرًا مِنَ النّاسِ بِلِقاءِ رَبِّهِم لَكافِرونَ

Muhammad Asad

Have they never learned to think for themselves?¹ God has not created the heavens and the earth and all that is between them without [an inner] truth and a term set [by Him]:² and yet, behold, there are many people who stubbornly deny the truth that they are destined to meet their Sustainer!

Lit., "Have they never thought within themselves?"
I.e., in contrast to God, who is eternal and unlimited, everything created is limited and subject to change and termination. As regards my rendering of illa bi'l-haqq (lit., "otherwise than with [or "in"] truth") as "without [an inner] truth", see note 11 on the second sentence of 10:5.
