Mukhtasar Muslim

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said: "Have you heard about a city, one side of which is on land and the other side is on the sea?" The companions said, "Yes, O Messenger of Allah! We have heard (i.e., it is Constantinople)." He (peace and blessings of Allah be upon him) said: "The Hour will not be established until seventy thousand people from the descendants of Ishaq (Isaac) fight against this city. When they reach near this city, they will camp there. They will not fight with weapons nor shoot arrows, but they will say: ((La ilaha illallah wallahu akbar)), and the side of it that is by the sea will fall. Then they will say ((La ilaha illallah wallahu akbar)) a second time, and its other side will fall. Then they will say ((La ilaha illallah wallahu akbar)) a third time, and it will open from all sides. Thus, they will enter the city and seize the spoils of war. While they are distributing the spoils, suddenly a caller will come and announce that the Dajjal has emerged, so they will leave everything and return (towards the Dajjal)."
