وَعَنْ عَبْدِ اللَّهِ بْنِ بُسْرٍ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ”بَيْنَ الْمَلْحَمَةِ وَفَتْحِ الْمَدِينَةِ سِتُّ سِنِينَ وَيَخْرُجُ مَسِيحُ الدَّجَّالِ فِي السَّابِعَةِ“
It is narrated from Sayyiduna Abdullah bin Busr (may Allah be pleased with him), the Messenger of Allah (peace and blessings be upon him) said: There will be a gap of six years between the great bloodshed and the conquest of Constantinople, and in the seventh year the Dajjal will appear.
