Surah 26. Ash-Shuara, Ayah 9

The above two verses appear eight times in this surah. Apart from the present instance, they conclude, like a refrain, each of the subsequent seven stories of earlier prophets, which - by means of their, in places, almost identical phrasing - are meant to stress the essential identity of the ethical teachings of all the prophets, as well as to illustrate the statement, in verse {5}, that a rejection of God's messages is a recurrent phenomenon in the history of mankind despite the fact that His existence is clearly manifested in all living creation.

One Who is able to carry out all His Will and Plans. See n. 2818 to xxii. 40.
