Prophet ^Isa (Jesus) received a Heavenly Book, the Injil, which contained the Shari^ah, (rules of the Religion) revealed to him. In it was the prohibition of associating partners with Allah. In it was the prohibition to consume the usurious gain (riba), pig meat, blood, and the meat of animals not slaughtered properly. It contained the order to perform the Prayer (with bowing and prostration) twice a day. It had the order to fast (but other than the month of Ramadan), and the order to perform taharah.
Prophet ^Isa came with a Shari^ah that contained making permissible some of the things which had been forbidden upon the children of Israel in the Torah. Although what is called "The Bible" today contains some true stories of Prophet ^Isa, it does not contain the true Injil which was revealed to him.
