A. Yusuf Ali:Translation:
There is, in their stories, 1796 instruction for men
endued with understanding. It is not a tale invented,
but a confirmation of what went before it,- 1797 a
detailed exposition of all things, and a guide and a
mercy to any such as believe.

Muhammad Asad:Translation:
Indeed, in the stories of these men 108 there is a lesson for those who are endowed with insight. [As for this revelation, 109 ] it could not possibly be a discourse invented [by man]: nay indeed, 110 it is [a divine writ] confirming the truth of whatever there still remains [of earlier revelations], clearly spelling out everything, 111 and [offering] guidance and grace unto people who will believe.
1796 Their stories, i.e., the stories of the Prophets or of the wicked; for the two threads interwine, as in Joseph's story.
1797 A story like that of Joseph is not a purely imaginary fable. The People of the Book have it in their sacred literature. It is confirmed here in its main outline, but here there is a detailed spiritual exposition that will be found nowhere in earlier literature. The exposition covers all sides of human life. If properly understood, it gives valuable lessons to guide our conduct—an instance of Allah's grace and mercy to people who will go to Him in faith and put their affairs in His hands. @@@
