Yunus · 10:94

94. If you, O Messenger, are in doubt or confusion about the reality of the Qur’ān that I have revealed to you, then ask those Jews who read the Torah and the Christians who read the Gospel to confirm it. They will tell you that what was revealed to you is the truth because they have the description of it in their scriptures. The truth, about which there is no doubt, has come to you from your Lord, so do not be of those who have doubt.
