Majma al-Zawaid — Hadith 12551

Jubayr bin Nufayr narrates from his father that the Prophet (peace and blessings be upon him) mentioned the Dajjal and said: "If he emerges while I am among you, I will stand as a barrier against him on your behalf; and if he emerges when I am not among you, then every person will have to protect himself, and Allah Almighty will be, in my place, the guardian of every Muslim. Beware! One of his eyes will be wiped out, and he will resemble Abd al-Uzza bin Qatan al-Khuza'i. Beware! Between his two eyes will be written 'Kafir' (disbeliever), which every Muslim will read. Whoever of you meets him should recite Surah al-Fatihah before him. Beware! I have seen that he will emerge from a place between Syria and Iraq and will go to the right and to the left. O servants of Allah, remain steadfast!" He said this three times. It was said: "O Messenger of Allah! How fast will he move through the earth?" The Prophet (peace and blessings be upon him) said: "Like a cloud driven along by the wind." It was said: "O Messenger of Allah! How long will he remain on earth?" The Prophet (peace and blessings be upon him) said: "He will remain forty days, of which one day will be like a year, one day like a month, one day like a week, and the rest of the days like your ordinary days." The people said: "O Messenger of Allah! How will we perform the prayer at that time? Will we offer the prayers of one day, or will we make an estimate?" The Prophet (peace and blessings be upon him) said: "Rather, you will make an estimate for it."
Al-Tabarani recorded it. Its chain contains Abdullah bin Salih, who has been declared trustworthy, while a group declared him da'if (weak). The rest of its narrators are thiqat (trustworthy).
