Ma'arif al-Qur'an
Mufti Muhammad ShafiThe Surah began with the confirmation of Divine Oneness and the refutation of Trinity. Answered here are argumentations in which the disbelievers and deniers among the people of the Book persist - even after the truth of Islam has been proved conclusively. The advice against such ongoing. and unnecessary disputations is that the acceptance or rejection of disputers should be of no use to a believer who simply has to declare that he and those with him have entered the fold of Islam being in no doubt about its truth. The Holy Prophet ﷺ was entrusted with the mission of calling the people of the Book, the Jews and Christians, and the disbelievers of Arabia to submit to Allah and embrace Islam which will be for their own good for they will be on the right path. In case they continue to maintain their hostile attitude, the Holy Prophet ﷺ has been comforted here by saying that his duty is only limited to conveying the message of Allah and His commandments.
That the message does not seem to get across to them, as they elect to reject rather than accept, should really not be a matter of concern for him. This is something Allah will take care of in His own way for He is in full sight of what His servants are doing.
