Shahr bin Hawshab (may Allah have mercy on him) said: Sayyidah Asma' bint Yazid bin al-Sakan (may Allah be pleased with her), who was the paternal cousin of Sayyiduna Mu'adh (may Allah be pleased with him), narrated to me; she said: The Messenger of Allah (peace and blessings be upon him) came to me with some of his Companions, and he (peace and blessings be upon him) mentioned the Dajjal and said: "Before his emergence there will be three years, or a year, in which the sky will withhold a third of its rain and the earth a third of its produce; in the second year the sky will withhold two-thirds of its rain and the earth two-thirds of its produce; and in the third year the sky will withhold all that is in it and the earth all that is in it, so that every animal with molars and every animal with hooves will perish. And among the greatest of his trials is that he will say to a Bedouin: 'Tell me, if I bring your camels back to life for you, with large udders, long humps, plump and well-fed, will you not know that I am your Lord?' He will say: 'Yes.' Then Satan will appear before him (in that form)." Then the Messenger of Allah (peace and blessings be upon him) went out for some need of his, and I placed water for his ablution, and the people began sobbing so much that their voices rose. The Messenger of Allah (peace and blessings be upon him) took hold of the door and said: "What is the matter?" We said: "O Messenger of Allah! You have torn out their hearts with the mention of the Dajjal." The Messenger of Allah (peace and blessings be upon him) said: "If the Dajjal comes out while I am alive, then I will be the one to contend with him; and if I have died, then Allah is my successor over every believer." I said: "O Messenger of Allah! Then what will suffice the believers on that day?" He (peace and blessings be upon him) said: "What suffices the inhabitants of the heavens - glorification and sanctification (tasbih and taqdis) - will suffice them."
