Quran 11:14 — Hud (Hud)

If they fail to meet your challenge, then know that this is revealed with GOD's knowledge, and that there is no god except He. Will you then submit?

[11:13] If they say, "He fabricated (the Quran)," tell them, "Then produce ten suras like these, fabricated, and invite whomever you can, other than GOD, if you are truthful."*

[11:15] Those who pursue this worldly life and its material vanities, we will pay them for their works in this life, without the least reduction.
