1.The Jewish and Islamic concept of God is the same: one God, one person, one mind.This is same in Talmud, a central text of Rabbinic Judaism written between 200 CE/AD- 500 CE/AD.Thus it is different from the Triune God of Trinitarian Christianity, God as three persons, three minds, co-equal and co-eternal, one in essence, nature, power, action, and will.
2.The Talmud does contain references alleged to be a about Jesus Christ and his mother Miriam, where he is referred to as Yashu (believed by some Christians to be derogatory). For example:
Yashu is in Hell being boiled in hot excrement.” (Gittin 57a)
Yashu (Jesus) was sexually immoral and worshipped a brick.” (Sanhedrin 107b)
“Yashu (Jesus) was cut off from the Jewish people for his wickedness and refused to repent.” (Sotah 47a)
“Miriam the hairdresser had sex with many men.” (Shabbath 104b, Hebrew Edition only)
“She who was the descendant of princes and governors (the virgin Mary) played the harlot with carpenters.” (Sanhedrin 106a)
“Christians who reject the Talmud will go to hell and be punished there for all generations.” (Rosh Hashanah 17a)
However, this does not mean that what is written in Talmud is what all Jewish people believe or practise or most of them for that matter.It only reflects Rabbinic exegeses and commentaries.
