“The Messenger of Allah ﷺ said: ‘Does not the one who raises his head before the Imam fear that Allah may turn his head into the head of a donkey?’” (Using translation from Ibn Mājah 961)
قَالَ رَسُولُ اللهِ ﷺ أَمَا يَخَافُ الَّذِي يَرْفَعُ رَأْسَهُ قَبْلَ الْإِمَامِ أَنْ يُحَوَّلَ رَأْسُهُ رَأْسَ حِمَارٍ
