حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنَا بَقِيَّةُ، عَنْ بَحِيرِ بْنِ سَعْدٍ، عَنْ خَالِدِ بْنِ أَبِي بِلاَلٍ، عَنْ عَبْدِ اللَّهِ بْنِ بُسْرٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ بَيْنَ الْمَلْحَمَةِ وَفَتْحِ الْمَدِينَةِ سِتُّ سِنِينَ وَيَخْرُجُ الدَّجَّالُ فِي السَّابِعَةِ "
It was narrated from 'Abdullah bin Busr that the Messenger of Allah (ﷺ) said:
"Between the fierce battle and the conquest of Al-Madinah will be six years, and the appearance of Dajjal will come in the seventh.'"
