Some verses of the Holy Quran say that Isa(as) has died.
(3-145)
وَمَا مُحَمَّدٌ اِلَّا رَسُوۡلٌ ۚ قَدۡ خَلَتۡ مِنۡ قَبۡلِہِ الرُّسُلُ ؕ اَفَا۠ئِنۡ مَّاتَ اَوۡ قُتِلَ انۡقَلَبۡتُمۡ عَلٰۤی اَعۡقَابِکُمۡ ؕ وَمَنۡ یَّنۡقَلِبۡ عَلٰی عَقِبَیۡہِ فَلَنۡ یَّضُرَّ اللّٰہَ شَیۡئًا ؕ وَسَیَجۡزِی اللّٰہُ الشّٰکِرِیۡنَ ﴿۱۴۵
And [a]Muhammad is but a Messenger. Verily, all Messengers have passed away before him. If then he dies or is slain, will you turn back on your heels? And he who turns back on his heels shall not harm Allah at all.[494] And Allah will certainly reward the grateful.
(5-117)
وَاِذۡ قَالَ اللّٰہُ یٰعِیۡسَی ابۡنَ مَرۡیَمَ ءَاَنۡتَ قُلۡتَ لِلنَّاسِ اتَّخِذُوۡنِیۡ وَاُمِّیَ اِلٰہَیۡنِ مِنۡ دُوۡنِ اللّٰہِ ؕ قَالَ سُبۡحٰنَکَ مَا یَکُوۡنُ لِیۡۤ اَنۡ اَقُوۡلَ مَا لَیۡسَ لِیۡ ٭ بِحَقٍّ ؕ اِنۡ کُنۡتُ قُلۡتُہٗ فَقَدۡ عَلِمۡتَہٗ ؕ تَعۡلَمُ مَا فِیۡ نَفۡسِیۡ وَلَاۤ اَعۡلَمُ مَا فِیۡ نَفۡسِکَ ؕ اِنَّکَ اَنۡتَ عَلَّامُ الۡغُیُوۡبِ ﴿۱
And when Allah will say, “O Jesus, son of Mary, didst thou say to men, ‘Take me and my mother for two gods[811] beside Allah?’”, He will answer, “Holy art Thou, I could never say[812] that to which I had no right.

مَا قُلۡتُ لَہُمۡ اِلَّا مَاۤ اَمَرۡتَنِیۡ بِہٖۤ اَنِ اعۡبُدُوا اللّٰہَ رَبِّیۡ وَرَبَّکُمۡ ۚ وَکُنۡتُ عَلَیۡہِمۡ شَہِیۡدًا مَّا دُمۡتُ فِیۡہِمۡ ۚ فَلَمَّا تَوَفَّیۡتَنِیۡ کُنۡتَ اَنۡتَ الرَّقِیۡبَ عَلَیۡہِمۡ ؕ وَاَنۡتَ عَلٰی کُلِّ شَیۡءٍ شَہِیۡدٌ ﴿۱۱۸
“I said nothing to them except that which Thou didst command me—‘Worship Allah, my Lord[813] and your Lord.’ And I was a witness over them as long as I remained among them,[814] but since [a]Thou didst cause me to die,[815] Thou hast been the Watcher over them, and Thou art Witness over all things;
