قُلْ سِيرُوا۟ فِى ٱلْأَرْضِ ثُمَّ ٱنظُرُوا۟ كَيْفَ كَانَ عَـٰقِبَةُ ٱلْمُكَذِّبِينَ
Qul seeroo fil ardi summan zuroo kaifa kaana 'aaqibatul mukazzibeen
De ki: "Yeryüzünde gezip dolaşın, sonra da, yalanlayanların sonunun nasıl olduğuna bir bakın."
Say, "Travel through the earth, then see what became of those who denied the truth."
A demand for an angel gets answered with a command to go outside and look at ruins. ʿĀqiba names what follows a thing rather than the thing itself, so what the traveller is sent to weigh is how these stories ended. The order of the two verbs carries weight as well: the walking comes first, and the judgment is asked for only afterwards.
