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 Messenger of Allah ﷺ. He mentioned many similar things.
