It was narrated from 'Abdullah bin Busr that the Messenger of Allah 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.'"
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 " .
