The story of Joseph in the Qur'an moves in a stream from beginning to end; its substance and form are equally coherent. It documents the execution of God's rulings despite the challenge of human intervention
"And Allah hath full power and control over His affairs; but most among mankind know it not." Q 12:21
This is what the story of Joseph confirms categorically, for it ends with comfort and marvels, which is described in Quran.
