It was narrated that Abu Hurairah said:“The Messenger of Allah (ﷺ) said to a man: ‘What do you say during your Salat?’ He said: ‘The Tashah-hud, then I ask Allah for Paradise, and I seek refuge with Him from Hell, but I do not understand what you and Mu’adh murmur (during Salat). He said: ‘Our murmuring revolves around the same things.’”
حَدَّثَنَا يُوسُفُ بْنُ مُوسَى الْقَطَّانُ، حَدَّثَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، عَنْ أَبِي صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ لِرَجُلٍ " مَا تَقُولُ فِي الصَّلاَةِ " . قَالَ أَتَشَهَّدُ ثُمَّ أَسْأَلُ اللَّهَ الْجَنَّةَ وَأَعُوذُ بِهِ مِنَ النَّارِ أَمَا وَاللَّهِ مَا أُحْسِنُ دَنْدَنَتَكَ وَلاَ دَنْدَنَةَ مُعَاذٍ . فَقَالَ " حَوْلَهُمَا نُدَنْدِنُ " .
