وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، حَدَّثَنَا مَعْمَرٌ، عَنْ هَمَّامِ بْنِ مُنَبِّهٍ، قَالَ هَذَا مَا حَدَّثَنَا أَبُو هُرَيْرَةَ، عَنْ مُحَمَّدٍ، رَسُولِ اللَّهِ صلى الله عليه وسلم فَذَكَرَ أَحَادِيثَ مِنْهَا وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا قَامَ أَحَدُكُمْ مِنَ اللَّيْلِ فَاسْتَعْجَمَ الْقُرْآنُ عَلَى لِسَانِهِ فَلَمْ يَدْرِ مَا يَقُولُ فَلْيَضْطَجِعْ .
Abu Huraira reported Allah's Messenger (ﷺ) as saying: When any one of you gets up at night (for prayer) and his tongue falters in (the recitation) of the Qar'an, and he does not know what he is reciting, he should go to sleep.
