«عمران بيت المقدس خراب يثرب وخراب يثرب خروج الملحمة وخروج الملحمة فتح القسطنطينية وفتح القسطنطينية خروج الدجال»
The Prophet (peace and blessings be upon him) said:
"The flourishing of Bayt al-Maqdis is a sign of the ruin of Yathrib, the ruin of Yathrib is a sign of the outbreak of the great battle, the outbreak of the great battle is a sign of the conquest of Constantinople, and the conquest of Constantinople is a sign of the emergence of the Dajjal."
