Say O People of the Scripture! Ye have naught (of guidance) till ye observe the Torah and the Gospel and that which was revealed unto you from your Lord. That which is revealed unto thee (Muhammad) from thy Lord is certain to increase the contumacy and disbelief of many of them. But grieve not for the disbelieving folk.
Lo! those who believe, and those who are Jews, and Sabaeans, and Christians - Whosoever believeth in Allah and the Last Day and doeth right - there shall no fear come upon them neither shall they grieve.
We made a covenant of old with the Children of Israel and We sent unto them messengers. As often as a messenger came unto them with that which their souls desired not (they became rebellious). Some (of them) they denied and some they slew.
They thought no harm would come of it, so they were wilfully blind and deaf. And afterward Allah turned (in mercy) toward them. Now (even after that) are many of them wilfully blind and deaf. Allah is Seer of what they do.
They surely disbelieve who say: Lo! Allah is the Messiah, son of Mary. The Messiah (himself) said: O Children of Israel, worship Allah, my Lord and your Lord. Lo! whoso ascribeth partners unto Allah, for him Allah hath forbidden paradise. His abode is the Fire. For evil-doers there will be no helpers.
They surely disbelieve who say: Lo! Allah is the third of three; when there is no Allah save the One Allah. If they desist not from so saying a painful doom will fall on those of them who disbelieve.
Will they not rather turn unto Allah and seek forgiveness of Him? For Allah is Forgiving, Merciful.
The Messiah, son of Mary, was no other than a messenger, messengers (the like of whom) had passed away before him. And his mother was a saintly woman. And they both used to eat (earthly) food. See how We make the revelations clear for them, and see how they are turned away!
Say: Serve ye in place of Allah that which possesseth for you neither hurt nor use? Allah it is Who is the Hearer, the Knower.
Say: O People of the Scripture! Stress not in your religion other than the truth, and follow not the vain desires of folk who erred of old and led many astray, and erred from a plain road.
