Do they not contemplate within themselves?1 Allāh has not created the heavens and the earth and what is between them except in truth and for a specified term. And indeed, many of the people, in the meeting with their Lord, are disbelievers.
Translation: Saheeh International (English)
1 An additional meaning is "Do they not contemplate concerning themselves."
Do these rejecting idolaters not ponder in themselves as to how Allah has created them and arranged them together in their most complete forms? Allah did not create the heavens and the earth except for a just cause; He did not create them in vain and He appointed a fixed time for their existence in the world. Indeed, many people reject the meeting of their Lord on the Day of Judgement, and that is why they are not prepared for the resurrection by doing good deeds which are acceptable to their Lord.
