“I memorized two pauses in the prayer, a pause before reciting and a pause when bowing. ‘Imran bin Husain denied that, so they wrote to Al-Madinah, to Ubayy bin Ka’b, and he said that Samurah was speaking the truth.”
Sunan Ibn Majah Book 5, Hadith 43
← Previous Hadith “There are two pauses which I memorized from the Messenger of Allah (ﷺ), but `Imran bin Husain denied that. We wrote to Ubayy bin Ka`b in Al-Madinah, and he wrote that Samurah had indeed memorized them.”

(One of the narrators) Sa`eed said: "We said to Qatadah: 'What are these two pauses?' He said: 'When he started his prayer, and when he finished reciting.'

Then later he said: 'And when he recited: 'Not (the way) of those who earned your anger, nor of those who went astray.' They used to like (for the Imam) when he had finished reciting to remain silent until he had caught his breath.'"

Sunan Ibn Majah Book 5, Hadith 42 Next Hadith → “The Messenger of Allah (ﷺ) said: ‘The Imam has been appointed to be followed, so when he says Allahu Akbar, then say Allahu Akbar, when he recites, then listen attentively; when he says: Not (the way) of those who earned Your anger, nor of those who went astray, then say Amin; when he bows then bow; when he says Sami’ Allahu liman hamidah (Allah hears those who praise Him), then say Allahumma Rabbana wa lakal-hamd (O Allah, our Lord, to You is the praise);” when he prostrates then prostrate; and if he prays sitting down then all of you pray sitting down.’”
