Translation:

37. Nay! He has come with the (very) Truth and he confirms (the Message of) the apostles (before Him).

Notes (Tafseer)

4058. The message of Islam, so far from being "mad" or in any way peculiar, is eminently conformable to reason and the true facts of nature as created by Allah. It is the Truth in the purest sense of the term, and confirms the Message of all true Messengers that ever lived.
