Abū Sāliḥ reported on the authority of some Companions (radiy Allāhū ‘anhum) that the Prophet ﷺ said to a person: “What do you say in prayer?” He replied: “I first recite (the) tashahhud, and then I say [the above], but I do not understand your sound and the sound of Muʿādh (i.e. what you say or he says in prayer). The Prophet ﷺ said: “We too go around it (i.e. our supplication is also related to Paradise and Hell-fire).” (Abū Dāwūd 792)
