وَقالوا ما هِيَ إِلّا حَياتُنَا الدُّنيا نَموتُ وَنَحيا وَما يُهلِكُنا إِلَّا الدَّهرُ ۚ وَما لَهُم بِذٰلِكَ مِن عِلمٍ ۖ إِن هُم إِلّا يَظُنّونَ

And they say, "There is not but our worldly life; we die and live, and nothing destroys us except time." And they have of that no knowledge; they are only assuming.
