The follower should not raise his head before the imam in bowing or prostration
Hadith 134
أَخْبَرَنَا النَّضْرُ، نا شُعْبَةُ، نا مُحَمَّدُ بْنُ زِيَادٍ، قَالَ: سَمِعْتُ أَبَا هُرَيْرَةَ، يَقُولُ: قَالَ رَسُولُ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ، فَذَكَرَ مِثْلَهُ سَوَاءً، إِلَّا أَنَّهُ قَالَ: يُحَوِّلَ اللَّهُ رَأْسَهُ.
From another chain of narration, it is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) from the Messenger of Allah (peace and blessings be upon him) similar to the previous hadith, except that in this one he said: "Allah will change his head."
