Kathir bin Murrah Al-Hadrami narrated that :
He heard Abu Ad-Darda say: The Messenger of Allah (ﷺ) was asked: 'Is there recitation in every prayer?' He said: 'Yes.' A man among the Ansar said: 'Is that obligatory?' He (Abu Ad-Darda) turned to me (Kathir), as I was closest of the people to him, and said: 'I think that if the Imam leads the people, that is sufficient for them.'
