أَخْبَرَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، نا شُعْبَةُ، عَنْ مُحَمَّدِ بْنِ زِيَادٍ، عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ، عَنْ رَسُولِ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ: مَا يَخْشَى أَحَدُكُمْ إِذَا رَفَعَ رَأْسَهُ وَالْإِمَامُ سَاجِدٌ قَبْلَ الْإِمَامِ أَنْ يَجْعَلَ اللَّهُ رَأْسَهُ رَأْسَ حِمَارٍ أَوْ صُورَتَهُ صُورَةَ حِمَارٍ.
Sayyiduna Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Does any one of you not fear that if he raises his head before the Imam raises his head from prostration, Allah may turn his head into the head of a donkey or his appearance into the appearance of a donkey?"
