Christians need to read how Islam has abrogated the holiness of Jesus and Mary. Robert Spencer breaks it down for you. Via Jihad Watch:
This is another Meccan sura. In the first part of Muhammad’s career, a group of Muslims migrated from Arabia to Abyssinia. One of the Muslims recited the material here about Mary and Jesus to the Christian ruler of Abyssinia, showing him that Muslims believed in Jesus, but not as the Son of God.
After the mysterious letters in v. 1, verses 2-40 retell the story told in Luke 1:5-80 – with some important differences, of course. Vv. 2-15 begin, as does Luke’s account, with the story of Zechariah, the father of John the Baptist, encountering an angel (Luke 1:11; v. 9 of this chapter of the Qur’an establishes that Allah is not speaking directly with Zechariah). The angel tells him he will become a father despite his old age and his wife’s barrenness (v. 8). In the Qur’an, unlike in the Gospel, this comes as an answer to his prayer for a son (vv. 4-6). In both the Gospel (Luke 1:20) and the Qur’an (v. 10) he is unable to speak after this vision, although the Qur’an, unlike the Gospel, does not present this as punishment for his unbelief, but only as a sign of Allah’s power.
