Musannaf Ibn Abi Shaybah

Hazrat Tawus narrates that when Hazrat Mu'adh came to Yemen, people brought to him the intermediate number between the two prescribed amounts for honey and goats (for example, if there are five camels, the zakat is only one goat, and until their number reaches ten, there will be no increase; thus, from five to ten is called 'waqs'). He said: I have not been commanded (to collect zakat) regarding them.
