“I have never seen anyone whose prayer more closely resembles that of the Messenger of Allah (ﷺ) than so-and-so. He used to lengthen the first two Rak’ah of the Zuhr and shorten the last two Rak’ah, and he used to shorten the ‘Asr.”
Sunan Ibn Majah Book 5, Hadith 25
← Previous Hadith “I said to Khabbab: ‘How did you recognize that the Messenger of Allah (ﷺ) was reciting in the Zuhr and the ‘Asr?’ He said: ‘From the movement of his beard.’”

Sunan Ibn Majah Book 5, Hadith 24 Next Hadith → “Thirty of the Companions of the Messenger of Allah (ﷺ) who had been at Badr came together and said: ‘Come, let us estimate the length of the recitation of the Messenger of Allah (ﷺ) for the prayer in which Qur’an is not recited out aloud.’ No two men among them disagreed, and they estimated the length of his recitation in the first Rak’ah of the Zuhr to be thirty Verses and in the second Rak’ah to be half of that. They estimated his recitation in ‘Asr to be half of the last two Rak’ah of Zuhr.”

Sunan Ibn Majah Book 5, Hadith 26
