Musnad Ahmad 2232

'Abdullah bin 'Ubaidullah bin ‘Abbas narrated: Some young men of Quraish and I entered upon Ibn 'Abbas (رضي الله عنه) and asked him: Did the Messenger of Allah (ﷺ) recite Qurʼan in Zuhr and "Asr? He said: No. They said: Perhaps he was reciting to himself. He said: Woe to you! This is worse than the first (thing you said). The Messenger of Allah (ﷺ) was just a slave who followed instructions and conveyed that with which he was sent. He did not say anything to us alone to the exclusion of the people, except in three things; he instructed us to do wudoo' properly, not to consume zakah, and not to mate a donkey with a mare.
