Quran 11:62 — Hud (Hud)

They said, "O Sãleh, you used to be popular among us before this. Are you enjoining us from worshiping what our parents are worshiping? We are full of doubt concerning everything you have told us."

[11:61] To Thamoud we sent their brother Sãleh. He said, "O my people, worship GOD; you have no other god beside Him. He initiated you from the earth, then settled you in it. You shall seek His forgiveness, then repent to Him. My Lord is always near, responsive."

[11:63] He said, "O my people, what if I have solid proof from my Lord, and mercy from Him? Who would support me against GOD, if I disobeyed Him? You can only augment my loss.
