" Commentary : Allah has offered more than adequate reasons as to why people must be believers. The Qur'an is a miracle on its own and, at the same time, a person like Ali- ibn- Abi- Talib(a.s.), is also a witness which testifies to its authenticity. Moreover, the Torah had also provided good tidings as to the emergence of the Qur'an long before it was revealed.
Therefore, the Qur'an inquires whether he who brings clear evidence from his Lord, who is supported by a testifying witness, who is commissioned by Allah, and before whom the Book of Moses(Torah)had come bringing revelations as the forerunner of future blessings to come and heralding his magnitude to be regarded as equal to those who lack all these qualities, signs, and proofs.
The verse says: " Is he then(like unto him)who has a clear proof from his Lord and follows him a witness from Him, and before it(is)the Book of Moses, a guide and a mercy(testifying it)"?
He is no one but the (p.b.u.h.) and/ bayyinah/ or the clear evidence he offers, is the glorious Qur'an, and his witness, who testifies as to the truthfulness of his prophecy amongst the believers is none other than that righteous believer, Ali(a.s.), whose signs and characteristics had been depicted in the Torah long before his historical appearance. Therefore, the authenticity of his mission has been verified in three ways: First, the Qur'an which is a clear evidence in his hands.
Secondly, the previous holy Books which have precisely explained his signs, and whose adherents were very familiar with those signs during the era of the Prophet(p.b.u.h.) .
