Quran 25:31 — The Statute Book (Al-Furqan)

We also set up against every prophet enemies from among the guilty. Your Lord suffices as a guide, a master.

[25:30] The messenger* said, "My Lord, my people have deserted this Quran."

[25:32] Those who disbelieved said, "Why did not the Quran come through him all at once?" We have released it to you gradually, in order to fix it in your memory. We have recited it in a specific sequence.
