"Thirty of theCompanions of the Messenger of Allah (ﷺ) who had been at Badr cametogether and said: 'Come, let us estimate the length of therecitationof the Messenger of Allah (ﷺ) for the prayer in whichQur'an is notrecited out aloud.' No two men among themdisagreed, and theyestimated the length of his recitation in thefirst Rak'ah of the Zuhrto be thirty Verses and in the secondRak'ah to be half of that. Theyestimated his recitation in 'Asrto be half of the last two Rak'ah ofZuhr." (AR)
