Sunan at-Tirmithiy كتاب الصلاة باب ما جاء ما يقول الرجل إذا أذن المؤذن

حَدَّثَنَا هَنَّادٌ حَدَّثَنَا جَرِيرٌ عَنْ مَنْصُورٍ عَنْ هِلاَلِ بْنِ يِسَافٍ عَنْ زِيَادِ بْنِ أَبِى الْجَعْدِ عَنْ عَمْرِو بْنِ الْحَارِثِ بْنِ الْمُصْطَلِقِ قَالَ كَانَ يُقَالُ أَشَدُّ النَّاسِ عَذَابًا يَوْمَ الْقِيَامَةِ اثْنَانِ امْرَأَةٌ عَصَتْ زَوْجَهَا وَإِمَامُ قَوْمٍ وَهُمْ لَهُ كَارِهُونَ. قَالَ هَنَّادٌ قَالَ جَرِيرٌ قَالَ مَنْصُورٌ فَسَأَلْنَا عَنْ أَمْرِ الإِمَامِ فَقِيلَ لَنَا إِنَّمَا عَنَى بِهَذَا أَئِمَّةً ظَلَمَةً فَأَمَّا مَنْ أَقَامَ السُّنَّةَ فَإِنَّمَا الإِثْمُ عَلَى مَنْ كَرِهَهُ.
It was said that the people who would receive the severest punishment on the Day of Resurrection would be of two [kinds]: a woman who disobeyed her husband; and a man who led people in prayer despite being hated by them (1).
[1]This applies to Imāms who are transgressors, and not to those who follow the sunnah (the Prophet's tradition).
