‘Amr b. Shu'aib, quoting his father on the authority of his grandfather, said that a nomadic Arab came to the Prophet and asked him about ablution. He demonstrated it, performing each detail three times and then said, “This is how ablution should be performed. If anyone does more than this, he has done wrong, transgressed, and done wickedly.” Nasa’i and Ibn Majah transmitted it, and Abu Dawud transmitted something to the same effect.
