Allah said,

[فَـَامَنَت طَّآئِفَةٌ مِّن بَنِى إِسْرَءِيلَ وَكَفَرَت طَّآئِفَةٌ]

(Then a group of the Children of Israel believed and a group disbelieved.) When `Isa, peace be on him, conveyed the Message of his Lord to his people and the disciples supported him, a group from the Children of Israel believed. They accepted the guidance that `Isa brought to them, while another group, was led astray. This group rejected what `Isa brought them, denied his prophethood and invented terrible lies about him and his mother. They are the Jews, may Allah curse them until the Day of Judgement. Another group exaggerated over `Isa, until they elevated him to more than the level of prophethood that Allah gave him. They divided into sects and factions, some saying that `Isa was the son of Allah, while others said that he was one in a trinity, and this is why they invoke the father, the son and the holy ghost! Some of them said that `Isa was Allah, as we mentioned in the Tafsir of Surat An-Nisa'.
