Quran 21:109 — The Prophets (Al-Anbya')

فَإِن تَوَلَّوا فَقُل ءاذَنتُكُم عَلىٰ سَواءٍ ۖ وَإِن أَدرى أَقَريبٌ أَم بَعيدٌ ما توعَدونَ

If they turn away, then say, "I have warned you sufficiently, and I have no idea how soon or late (the retribution) will come to you.

[21:108] Proclaim, "I have been given divine inspiration that your god is one god. Will you then submit?"

[21:110] "He is fully aware of your public utterances, and He is fully aware of everything you conceal.
