Abu Dawud Book 3, Hadith Number 1556.

Narated By Imran ibn Husayn : Habib al-Maliki said: A man said to Imran ibn Husayn: AbuNujayd, you narrate to us traditions whose basis we do not find in the Qur’an.

Thereupon, Imran got angry and said to the man: Do you find in the Qur’an that one dirham is due on forty dirhams (as Zakat), and one goat is due on such-and-such number of goats, and one camel will be due on such-and-such number of camels?

He replied: No.

He said: From whom did you take it? You took it from us, from the Apostle of Allah (PBUH).

He mentioned many similar things.
