They thought that what they did would not be a Fitnah (mischief), so they became blind and deaf (they were unable to see and hear the truth). After that Allah accepted their repentance. Then many of them became blind and deaf again. And Allah sees the best of what they do.
Certainly those who said: “Surely Allah, He is the Messiah, son of Mary became the disbelievers”. Yet the Messiah (Jesus) told them: “O Children of Israel! Be servants to Allah, my Lord and your Lord. Surely whoever associates (other things) with Allah, then Allah has forbidden to him Heaven and his abode is the Fire. And there are no helpers for the wrong-doers”.
Certainly they have disbelieved who said: “Surely Allah is the third of the three (one god out of the Trinity)”. And there is no deity but the only Deity. And if they do not desist from what they (insist to) say, a painful torment will fall on those of them who disbelieve.
Do they still not then turn with repentance to Allah and ask for His Forgiveness? And Allah is Oft-Forgiving, Most Merciful.
The Messiah (Jesus), son of Mary, is but a Messenger. Messengers before him have indeed passed away. And his mother was a Sıddîk (truthful, just). They both used to eat food (just like everybody else). See how We make the Verses clear to them. Then look, how they are deluded (from Allah).
Say: “Do you become servants to things other than Allah which has no power to harm or benefit you”? And Allah, He is All-Hearing, All-Knowing.
