Mishkat al-Masabih 4 Prayer كتاب الصلاة 541

وَعَن سَلامَة بنت الْحر قَالَتْ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ مِنْ أَشْرَاطِ السَّاعَةِ أَنْ يَتَدَافَعَ أَهْلُ الْمَسْجِدِ لَا يَجِدُونَ إِمَامًا يُصَلِّي بِهِمْ» . رَوَاهُ أَحْمد وَأَبُو دَاوُد وَابْن مَاجَه

Sulama daughter of al-Hurr reported God’s Messenger as saying, “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.” Ahmad, Abu Dawud, and Ibn Majah transmitted it.
