Is there any proof that during the second coming of Jesus, may Allaah exalt his mention, he will marry and have kids?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah and that Muhammad is His slave and Messenger.

Many scholars mentioned that ʻEesa will get married and have children after his descent to Earth. Al-Qurtubi wrote:

"Kaʻb Al-Ahbaar said, 'ʻEesa (Jesus) will stay on Earth for forty years, during which people will lead a life filled with prosperity and abundance; blessings will descend in provisions, to the extent that a man will eat from a grape to his fill without finishing it, and a large group of people will sit to eat a bunch of grapes, and a pomegranate will be too heavy for a camel to carry ... ʻEesa will get married to a woman from such-and-such tribe and will have two sons with her. He will name one of them Muhammad and the other Moosa (Moses). Life will be very pleasant and enjoyable after Jesus' descent to Earth...'" [At-Tathkirah]

Ibn Katheer wrote, "His descent will be manifest as he would break the Cross, kill the pig, and marry a woman from Bani Jithaam. When he dies, he shall be buried in the room of the Prophet's Rawdhah (i.e. beside the grave of the Prophet )." [Al-Bidaayah wa An-Nihaayah]

There is no a marfooʻ hadeeth (a narration which is directly attributed to the Prophet ) reported in this regard as far as we know. It seems that this account is based on the reports narrated by the People of the Book as Al-Qurtubi attributed the above report to Kaʻb Al-Ahbaar .

Allaah knows best.
