The Qur'an in Surah 3:56 says Jesus died a natural death.
When Allah said, ‘O Jesus, I will cause thee to die a natural death and will exalt thee to Myself, and will clear thee from the charges of those who disbelieve, and will place those who follow thee above those who disbelieve, until the Day of Resurrection; then to Me shall be your return, and I will judge between you concerning that wherein you differ.
And in Surah 5:111
When Allah will say, “O Jesus, son of Mary, remember My favour upon thee and upon thy mother; when I strengthened thee with the Spirit of holiness so that thou didst speak to the people in the cradle and in middle age; and when I taught thee the Book and Wisdom and the Torah and the Gospel; and when thou didst fashion a creation out of clay, in the likeness of a bird, by My command; then thou didst breathe into it a new spirit and it became a soaring being by My command; and thou didst heal the night-blind and the leprous by My command; and when thou didst raise the dead by My command; and when I restrained the children of Israel from putting thee to death when thou didst come to them with clear Signs; and those who disbelieved from among them said, ‘This is nothing but clear deception.’”
