Arabic (Original)
حَدَّثَنَا إِسْمَاعِيلُ عَنْ يُونُسَ بْنِ عُبَيْدٍ عَنْ مُحَمَّدِ بْنِ زِيَادٍ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَا يَأْمَنُ الَّذِي يَرْفَعُ رَأْسَهُ فِي صَلَاتِهِ قَبْلَ الْإِمَامِ أَنْ يُحَوِّلَ اللَّهُ صُورَتَهُ صُورَةَ حِمَارٍ.
