[Hope]

˹Remember˺ when Allah said, “O Jesus! I will take you1 and raise you up to Myself. I will deliver you from those who disbelieve, and elevate your followers above the disbelievers until the Day of Judgment. Then to Me you will ˹all˺ return, and I will settle all your disputes.”Quran 3:55

If he is coming back alive on his second coming, He should have been raised alive 

As per your belief, was he raised alive?
Will he decend alive?

Lo! God said: "O Jesus! Verily, I shall cause thee to die, and shall exalt thee unto Me, and cleanse thee of [the presence of] those who are bent on denying the truth; and I shall place those who follow thee [far] above those who are bent on denying the truth, unto the Day of Resurrection. In the end, unto Me you all must return, and I shall judge between you with regard to all on which you were wont to differ. 45

Why is Allah so heartless that he needs to cause Jesus to die

Can you answer to my Question ?

As per your belief, was he raised alive?
Will he decend alive?
