Will Gog and Magog kill all the disbelievers, and if that happens, how will the Hour commence for the disbelievers?

Gog and Magog kill everyone they encounter, and they say they have killed those on Earth. Then they shoot their arrows towards the sky, and the arrows return to them stained with blood. Allah then destroys them by sending creatures that seize their necks. Jesus, peace be upon him, remains, and a new generation emerges, consisting of Muslims and disbelievers. Then Allah sends a gentle wind that takes the soul of every believer and Muslim, and only the worst of people remain, copulating like donkeys, and upon them, the Hour will be established.
