Musnad Ahmad 1304:8

Yazid ibn Harun narrated to us, Jarir ibn Hazim informed us, from Qatadah, from Shahr ibn Hawshab, from Asma bint Yazid, who said: We were with the Prophet, peace and blessings of Allah be upon him, in his house, and he said: "Three years before the emergence of the Dajjal, the sky will withhold a third of its rain, and the earth will withhold a third of its vegetation. In the second year, the sky will withhold two-thirds of its rain, and the earth will withhold two-thirds of its vegetation. In the third year, the sky will withhold all of its rain, and the earth will withhold all of its vegetation, so that no animal with a hoof or a cloven hoof will remain except that it will perish." "The Dajjal will say to a man from the desert dwellers: 'Do you see, if I were to resurrect your camels, with their udders large and their humps full, would you know that I am your Lord?' He will say: 'Yes.' Then the devils will appear to him in their form, so he will follow him. He will say to a man: 'Do you see, if I were to resurrect your father, your son, and those you know of your family, would you know that I am your Lord?' He will say: 'Yes.' Then the devils will appear to him in their forms, so he will follow him." Then the Messenger of Allah, peace and blessings of Allah be upon him, went out, and the people of the house wept. Then the Messenger of Allah, peace and blessings of Allah be upon him, returned while we were weeping, and he said: "What makes you weep?" I said: "O Messenger of Allah, what you mentioned of the Dajjal. By Allah, the mother of my family kneads her dough, and it does not reach the point of being baked before it is almost crumbling from hunger, so what shall we do on that day?" The Messenger of Allah, peace and blessings of Allah be upon him, said: "What will suffice the believers for food and drink on that day is the Takbir (saying Allahu Akbar), the Tasbih (saying SubhanAllah), and the Tahmid (saying Alhamdulillah)." Then he said: "Do not weep, for if the Dajjal emerges while I am among you, I will be his adversary, and if he emerges after me, then Allah is my successor over every Muslim."
