Judas Iscariot
There are several explanations as to why Judas betrayed Jesus. In the earliest account, in the Gospel of Mark, when he goes to the chief priests to betray Jesus, he is offered money as a reward, but it is not clear that money is his motivation. In the Gospel of Matthew account, on the other hand, he asks what they will pay him for handing Jesus over. In the Gospel of Luke and the Gospel of John, the devil enters into Judas, causing him to offer to betray Jesus. The Gospel of John account has Judas complaining that money has been spent on expensive perfumes to anoint Jesus which could have been spent on the poor, but adds that he was the keeper of the apostles' purse and used to steal from it.
Islamic views on Jesus' death
An early interpretation of verse 3:55 (specifically "I will cause you to die and raise you to myself"), Al-Tabari (d. 923 CE/310 AH) records an interpretation attributed to Ibn 'Abbas, who used the literal ""I will cause you to die"" (mumayyitu-ka) in place of the metaphorical mutawaffi-ka ""Jesus died"", while Wahb ibn Munabbih, an early Jewish convert, is reported to have said ""God caused Jesus, son of Mary, to die for three hours during the day, then took him up to himself."" Tabari further transmits from Ibn Ishaq Bishr: "God caused Jesus to die for seven hours", while at another place reported that a person called Sergius was crucified in place of Jesus. Ibn-al-Athir forwarded the report that it was Judas, the betrayer, while also mentioning the possibility it was a man named Natlianus.
