“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 مُحَمَّدٌ رَسُولُ اللهِ ﷺ أَمَا يَخْشَى الَّذِي يَرْفَعُ رَأْسَهُ قَبْلَ الْإِمَامِ أَنْ يَحُوِّلَ اللهُ رَأْسَهُ رَأْسَ حِمَارٍ  

[Machine] I heard Abu al-Qasim ﷺ saying, "Doesn't the one who raises his head while the imam is in prostration fear Allah? Wouldn't Allah make his head like the head of a donkey?" Shu'bah said in his narration or depiction of his words, "like the depiction of a donkey."  

سَمِعْتُ أَبَا الْقَاسِمِ ﷺ يَقُولُ أَمَا يَخْشَى اللهَ الَّذِي يَرْفَعُ رَأْسَهُ وَالْإِمَامُ سَاجِدٌ أَنْ يَجْعَلَ اللهُ رَأْسَهُ رَأْسَ حِمَارٍ قَالَ شُعْبَةُ فِي حَدِيثِهِ أَوْ صُورَتَهُ صُورَةَ حِمَارٍ  

[Machine] "He (Prophet Muhammad ﷺ) said: 'Doesn't anyone of you fear that when he raises his head from prostration before the Imam, Allah will transform his head into the head of a donkey?'"  

أَنَّهُ قَالَ قَالَ رَسُولُ اللهِ ﷺ أَمَا يَخَافُ أَحَدُكُمْ إِذَا رَفَعَ رَأْسَهُ مِنَ السُّجُودِ قَبْلَ الْإِمَامِ أَنْ يُحَوِّلَ اللهُ رَأْسَهُ رَأْسَ حِمَارٍ  

[Machine] "That the Imam has lifted up, so let him put his head down. When the Imam lifts his head up, let him stay for as long as he left. It has been narrated to us from Sha'bi and Ibrahim al-Nakha'i that he returns and prostrates."  

أَنَّ الْإِمَامَ قَدْ رَفَعَ فَلْيُعِدْ رَأْسَهُ فَإِذَا رَفَعَ الْإِمَامُ رَأْسَهُ فَلْيَمْكُثْ قَدْرَ مَا تَرَكَ وَرُوِّينَا عَنِ الشَّعْبِيِّ وَإِبْرَاهِيمَ النَّخَعِيِّ أَنَّهُ يَعُودُ فَيَسْجُدُ
