Sunan An-Nasa'i

It was narrated that 'Abdullah bin 'Ubaidullah bin 'Abbas said:I was with Ibn 'Abbas and a man asked him: ""Did the Messenger of Allah recite during Zuhr and 'Asr?"" He said: ""No."" He said: ""Perhaps he used to recite to himself?"" He said: ""May your face be scratched! This question is worse than the first one. The Messenger of Allah was a slave whose Lord commanded him and he conveyed (the message). By Allah, the Messenger of Allah did not specify anything for us above the people, except for three things: He commanded us to perform Wudu' properly, not to consume charity, and not to mate donkeys with horses
