Translation:

45. O Prophet! Truly We have sent thee as a Witness a Bearer of Glad Tidings and a Warner

Notes (Tafseer)

3734. The Prophet was sent by Allah in five capacities. Three are mentioned in this verse, and the other two in the verse following. (1) He comes as a Witness to all men about the spiritual truths which had been obscured by ignorance or superstition, or by the dust of sectarian controversy. He did not come to establish a new religion or sect. He came to teach Religion. He is also a witness to Allah about men's doings and how they receive Allah's Message: see iv. 41 and n. 560. (2) He comes as a bearer of the Glad Tidings of the Mercy of Allah. No matter how far men may have transgressed, they have hope if they believe, repent, and live a good life. (3) He also comes as a Warner to those who are heedless. This life will not last. There is a Future Life, and that is all-important. See next note.
