how many times did Allah Ta'ala specify in the Qur'an that he raised His Prophets or anyone for that matter - dead or alive? and don't forget to read the context: That they said (in boast), "We killed Christ Jesus the son of Mary, the Messenger of Allah";- but they killed him not, nor crucified him, but so it was made to appear to them, and those who differ therein are full of doubts, with no (certain) knowledge, but only conjecture to follow, for of a surety they killed him not: Nay, Allah raised him up unto Himself; and Allah is Exalted in Power, Wise; [4:157-158]
Points to note from these ayaat
1 - Christians claim that Jesus (peace be upon him) died on the cross, he was resurrected after three days and then raised up to heaven (ALIVE)
2 - Allah Ta'ala is refuting their belief that he (Jesus - peace be upon him) wasn't killed by them, nor crucified. Since he did not die, hence no resurrection. However, he was raised up. The disagreement among Muslims and Christians is on matter whether he was crucified or not. Following the sequence of events, if he was not killed by them that day but Allah raised him up how does it dispprove that he wasn't raised up alive?
