سنن أبي داود#581Da'ifحَدَّثَنَا هَارُونُ بْنُ عَبَّادٍ الأَزْدِيُّ، حَدَّثَنَا مَرْوَانُ، حَدَّثَتْنِي طَلْحَةُ أُمُّ غُرَابٍ، عَنْ عَقِيلَةَ، - امْرَأَةٌ مِنْ بَنِي فَزَارَةَ مَوْلاَةٌ لَهُمْ - عَنْ سَلاَمَةَ بِنْتِ الْحُرِّ، أُخْتِ خَرَشَةَ بْنِ الْحُرِّ الْفَزَارِيِّ قَالَتْ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " إِنَّ مِنْ أَشْرَاطِ السَّاعَةِ أَنْ يَتَدَافَعَ أَهْلُ الْمَسْجِدِ لاَ يَجِدُونَ إِمَامًا يُصَلِّي بِهِمْ " .
Narrated Sulamah daughter of al-Hurr: I heard the Messenger of Allah (ﷺ) say: One of the signs of the Last Hour will be that people in a mosque will refuse to act as imam and will not find an imam to lead them in prayer
