038 – Saad 

The chapter begins by denouncing those who covered up the truth for their opposition to Divine Guidance questioning, their logic. This is followed by lessons from past Prophets with a focus on Prophet Dawud. 
After a discussion of the blessings of Janna and the punishments of Jahannam there is a mention of the deniers of Jahannam who wonder why those whom they thought were astray were not with them in Jahannam.
The Prophets’ affirmation of Allah’s oneness is followed by the rebelliousness of Shaytaan when Prophet Adam was created. The chapter closes with a final address in which the Prophet is instructed to promise the Quraysh that they will eventually know the truth of revelation.
