Re: Isa (AS), Quran and his second coming:
Jesus(as) as per islamic teachings is a true prophet of Allah. He(as) was a human being just like us. There are many verses in Qur’an that indicate his death. Muslims also do believe in his second coming. However, the second coming of Jesus(as) does not necessarily mean the same Jesus(as) sent to bani israel, the one who was born in Palestine, since he has passed away. What the second coming means is that a prophet within the ummah of Muhammad PBUH will be born who will be given the title of Messiah, who will have almost identical duties as Jesus of bani israel and will fulfill all the prophecies Muhammad PBUH foretold.
There are no questions. Its very straight forward. World will not see peace just because Jesus(as) will come. You will have to believe in the one who will be given the title of Messiah, the like of Jesus(as) in the shariyah of Muhammad PBUH to attain peace. If you believe the second of Jesus(as) will happen the way orthodox Muslims or Christians believe then yeah, I can understand all the questions popping in your head.
