It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "On the night of Mi'raj, I met Hazrat Ibrahim, Hazrat Musa, and Hazrat Isa (peace be upon them). They began to discuss the Day of Resurrection, and this matter was presented before Hazrat Ibrahim (peace be upon him). He said, 'I have no knowledge of it.' Then it was presented before Hazrat Musa (peace be upon him), and he also said, 'I have no knowledge of it.' Then this matter was presented before Hazrat Isa (peace be upon him), and he said, 'No one has true knowledge of it except Allah. However, my Lord has informed me that near the Day of Resurrection, Dajjal will emerge. I will have two branches with me. As soon as Dajjal sees me, he will begin to melt just as tin melts. After that, Allah will cause him to be destroyed, until the trees and stones will call out, saying, "O Muslim! There is a disbeliever hiding beneath me, come and kill him." Thus, Allah will cause all of them to be destroyed. Then people will return to their cities and homelands. At that time, Gog and Magog will emerge, who will seem to be descending from every height. They will trample all the cities. I will supplicate to Allah against them, so Allah, the Exalted, will impose death upon them until the whole earth will be filled with their stench. Then Allah, the Exalted, will send rain which will wash away their bodies and throw them into the sea. (My father says that there is something here which I could not understand, nevertheless, the other narrator says:) After that, the mountains will be leveled and the earth will be stretched out like leather. My Lord has promised me that when these events occur, the example of the Day of Resurrection will be like that of a pregnant she-camel whose term has been completed, and its owner does not know when suddenly, during the day or night, it will give birth."
