Narrated Abdullah ibn Busr: The Prophet ﷺ said: The time between the great war and the conquest of the city (Constantinople) will be six years, and the Dajjal (Antichrist) will come forth in the seventh. Abu Dawud said: This is sounder than the tradition narrated by Isa (bin Yunus)

Hadith Takhrij« سنن ابن ماجہ/الفتن 35 (5194)، (تحفة الأشراف: 5194)، وقد أخرجہ: مسند احمد ( 4/189) (ضعیف) » (سند میں بقیہ بن ولید ضعیف اورابن ابی بلال لین الحدیث ہیں )
1؎: This hadith is in contradiction to the previous hadith, and both are weak. Reconciliation between the two is made in such a way that there will be a six-year interval between the beginning and end of the great battle, and the end of the great battle, the conquest of Constantinople, and the appearance of the Masih al-Dajjal will all occur close to each other, that is, within a period of seven months. Another answer is the one given by Abu Dawud, that the second hadith is more authentic in terms of its chain of transmission; therefore, the first hadith cannot be considered in opposition to it, because for contradiction, equal grounds are necessary.
