The Promised Messiah shall marry and have children

عَبْدُ اللہِ بْنِ عَمْرٍو قَالَ قَالَ رَسُوْلَ اللہِ صلّى الله عليه وسلّم یَنْزِلُ عِیْسَی ابْنُ مَرْیَمَ اِلَی الأَرْضِ فَیَتَزَوَّجُ وَیُوْلَدُلَہٗ

Hazrat Abdullah bin Amr^ra narrated, that “Allah’s Messenger^sa said, ‘Jesus, son of Mary, will descend on earth and shall marry and have children.’”
