6:34Other messengers before you were rejected, but they endured rejection and persecution until Our help came to them. There can be no change to God’s words. News of the Messengers has already reached you.

6:35If you find their rejection hard to bear, then if you can, seek a tunnel into the earth, or a stairway into the heaven, and bring them a sign. Had God willed, He could have gathered them to guidance. So do not be of the ignorant.
