Hadith 828
Chapter 38: Preceding the Imam - كتاب الإمامة
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ مُحَمَّدِ بْنِ زِيَادٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ مُحَمَّدٌ صلى الله عليه وسلم " أَلاَ يَخْشَى الَّذِي يَرْفَعُ رَأْسَهُ قَبْلَ الإِمَامِ أَنْ يُحَوِّلَ اللَّهُ رَأْسَهُ رَأْسَ حِمَارٍ " .
It was narrated that Abu Hurairah said:
"Muhammad (ﷺ) said: 'Does the one who raises his head before the Imam not fear that Allah may turn his head into the head of a donkey?"'
