AbuSalih reported on the authority of some Companions of the Prophet ﷺ: The Prophet ﷺ said to a person: what do you say in prayer? He replied: I first recite tashahhud (supplication recited in sitting position), and then I say: O Allah, I ask Thee for Paradise, and I seek refuge in Thee from Hell-Fire, but I do not understand your sound and the sound of Mu'adh (what you say or he says in prayer). The Prophet ﷺ said: We too go around it (paradise and Hell-fire).  

عَنْ بَعْضِ أَصْحَابِ النَّبِيِّ ﷺ قَالَ قَالَ النَّبِيُّ ﷺ لِرَجُلٍ كَيْفَ تَقُولُ فِي الصَّلاَةِ قَالَ أَتَشَهَّدُ وَأَقُولُ اللَّهُمَّ إِنِّي أَسْأَلُكَ الْجَنَّةَ وَأَعُوذُ بِكَ مِنَ النَّارِ أَمَا إِنِّي لاَ أُحْسِنُ دَنْدَنَتَكَ وَلاَ دَنْدَنَةَ مُعَاذٍ فَقَالَ النَّبِيُّ ﷺ حَوْلَهَا نُدَنْدِنُ  

“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.’”  

قَالَ رَسُولُ اللَّهِ ﷺ 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  

the Messenger of Allah (saas) said to a man: "What do you say during your prayer?" He said: "I recite the Tashah-hud then I ask for Allah for Paradise and see refuge with Him from Hell, but by Allah I do not understand your whispering or the whispering of Mu'adh." He said: "It is concerning them (Paradise and Hell) that we are whispering."  

قَالَ رَسُولُ اللَّهِ ﷺ لِرَجُلٍ مَا تَقُولُ فِي الصَّلاَةِ قَالَ أَتَشَهَّدُ ثُمَّ أَسْأَلُ اللَّهَ الْجَنَّةَ وَأَعُوذُ بِهِ مِنَ النَّارِ أَمَا وَاللَّهِ مَا أُحْسِنُ دَنْدَنَتَكَ وَلاَ دَنْدَنَةَ مُعَاذٍ قَالَ حَوْلَهُمَا نُدَنْدِنُ  

[Machine] The Messenger of Allah ﷺ said to a man, "What do you say in prayer?" The man replied, "I bear witness that there is no deity but Allah and I seek refuge in You from the Fire, O Allah, I ask You for Paradise."  

قَالَ رَسُولُ اللَّهِ ﷺ لِرَجُلٍ «مَا تَقُولُ فِي الصَّلَاةِ؟ » فَقَالَ أَتَشَهَّدُ ثُمَّ أَقُولُ اللَّهُمَّ إِنِّي أَسْأَلُكَ الْجَنَّةَ وَأَعُوذُ بِكَ مِنَ النَّارِ  

"حَوْلَهَا نُدَ نْدِن".

د عن بعض الصحابة قال: قال النبى ﷺ لرجل: "كيف تقول في الصلاة؟ (قال: أتَشَهَّدُ وأقولُ: اللهم إِنِّى أَسالُك الجنَّةَ، وأَعوذُ بك من النَّارِ، أمَا إِنِّى لَا أُحْسِنُ دَنْدَنَتَك وَلا دَنْدَنَةَ مُعاذِ" قال فذكره.
