The Messenger of Allah ﷺ said to a man, "What do you say in your prayer?"The man replied, "I recite the tashahhud, then I ask Allah for Paradise and seek refuge in Him from the Fire. By Allah, I cannot match your eloquent murmuring nor that of Muaz."He said, "It is around these very things that we murmur."
قال رسول الله ﷺ لرجل: ما تقول في الصلاة؟ قال: أتشهد ثم أسأل الله الجنة، وأعوذ به من النار. أما والله ما أحسن دندنتك ولا دندنة معاذ. فقال: حولها ندندن.
Ibn Majah (910, 3847) narrated it from Yusuf bin Musa Qattan, who said, "Jareer (bin Abdul-Hameed) told us, from Amash, from Abu Salih, from Abu Hurairah," and he related it. Its isnad is sahih. Ibn Khuzayma (725) also graded it sahih, narrating it from Yusuf bin Musa with the same wording, and Ibn Hibban (868) narrated it through Jareer bin Abdul-Hameed with the same wording.As for Abu Dawud (792), he narrated it from Uthman bin Abu Shayba, who said, "Husayn bin Ali told us, from Zaida, from Sulayman, from Abu Salih, from one of the companions of the Prophet ﷺ," and he related the same.As for his saying, "How excellent is your dandanah," this means your quiet, hidden petitioning. Dandanah is when a man speaks in a way that its sound can be heard but its words cannot be understood, and it is slightly louder than hainamah. The pronoun in "around it" refers to paradise, meaning around attaining it, or it refers to the fire, meaning around seeking refuge from it. This is stated as such in Nihayah (2/137).
