Can he, then, who possesses a clear proof from his Lord, and to testify to whose truth a witness from Him shall follow him, and who was preceded by the Book of Moses, a guide and a mercy, be an impostor? (11:18)
Three arguments have been given here in support of the truth of the Holy Prophet Muhammad, may peace by upon him.
1. He possesses clear proof from his Lord
2. To testify to whose truth a witness shall follow him.
3. He was preceded by the Book of Moses, which testified to his truth.
The witness to follow the Holy Prophet is the Messiah and the Mahdi. As described in various traditions he would be from the followers of the Holy Prophet and would come at the head of the fourteenth century hijra. This prophecy was fulfilled in the person of Mirza Ghulam Ahmad of Qadian, India (1835-1908).
