حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا عَبْدُ الْوَارِثِ، حَدَّثَنَا أَبُو التَّيَّاحِ، عَنْ صَخْرِ بْنِ بَدْرٍ الْعِجْلِيِّ، عَنْ سُبَيْعِ بْنِ خَالِدٍ، بِهَذَا الْحَدِيثِ عَنْ حُذَيْفَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ فَإِنْ لَمْ تَجِدْ يَوْمَئِذٍ خَلِيفَةً فَاهْرَبْ حَتَّى تَمُوتَ فَإِنْ تَمُتْ وَأَنْتَ عَاضٌّ ‏"‏ ‏.‏ وَقَالَ فِي آخِرِهِ قَالَ قُلْتُ فَمَا يَكُونُ بَعْدَ ذَلِكَ قَالَ ‏"‏ لَوْ أَنَّ رَجُلاً نَتَجَ فَرَسًا لَمْ تُنْتَجْ حَتَّى تَقُومَ السَّاعَةُ ‏"‏ ‏.‏

The tradition mentioned above has also been transmitted by Hudhaifah through a different chain of narrators from the Prophet (PBUH). This version says: He said: If you do not find a caliph in those days, then flee away until you die, even of you die holding on (to a stump of a tree). I asked: What will come next ? He replied: If a man wants the mare to bring forth a foal, it will not deliver in till the Last Hour comes. Translation Not Available
