JESUS (PBUH) SAID, "THE DAY THAT I DIE", not "THE DAY THAT I DIED"
It is mentioned in Surah Maryam, Chapter 19 verse 33 "So Peace is on me the day I was born, the day that I die and the Day that I shall be raised up to life (again)". [Al-Qur'ân 19:33]
The Qur'ân mentions that Jesus (pbuh) said "Peace is on me the Day I was born, the day that I die". It is not stated: "the day that I died". It is in the future tense and not in the past tense.
JESUS (PBUH) WAS RAISED UP ALIVE
The Qur'ân further says in Surah Nisa, Chapter 4 verse 157-158:
"That they said (in boast), ‘We killed Jesus Christ 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." [Al-Qur'ân 4:157-158]
