Notes (Tafseer)

4219. Cf. xii. 39, where Joseph preaches to the men in prison. The one supreme Message of importance to mankind was (and is) the Unity of Allah: that He is the Creator and Sustainer of all: that His Will is supreme; that He can carry out His Will without question, and no powers of Evil can defeat it; and that He forgives by His grace again and again. This Message the holy Prophet came to deliver, and he delivered it.
