Kitab al-Fitan · Nu'aym ibn Hammad

The one who takes it will regret not having increased, and the one who leaves will regret not having taken it. Indeed, what they acquired from it will be a help to them in the years of hardship and the years of the Dajjal.

The great epic, the destruction of Constantinople, and the emergence of the Dajjal, in seven months, or as long as Allah wills

The Dajjal will not emerge until Constantinople is conquered

The news comes to them that the Dajjal has left after they conquered Constantinople, so they leave but do not find him. They only stay for a short time until he leaves.

They conquer Constantinople, and news of the Dajjal comes to them, so they go out to the Levant, and find that he has not left, and then it is not long before he leaves.

The news comes to them after its conquest, meaning Constantinople, and they reject what they have in their hands, so they go out and find it to be false. The Dajjal will not come out until after that, and a snake clings to him by the side of the sea, then he comes out.

While they were dividing the spoils of Constantinople, when news of the Dajjal came to them, they rejected what was in their hands, then they approached and joined Jerusalem, and he prayed behind the one who followed the command of the Muslims. Then Allah Almighty inspired Jesus, son of Mary, to go to Gog and Magog, then the earth pays its zakat as it was at the beginning of the world, then he stays for seven days, then Allah sends a wind and it takes the souls of the believers.
