Musannaf Ibn Abi Shaybah

Hazrat Umair narrates that we used to give something as a gift, etc., to the goat herders on the condition that they would give us such and such amount of cheese, such and such amount of ghee, and such and such amount of a yellow liquid substance. Then I inquired about this from Hazrat Alqama, Hazrat Masrooq, and Hazrat Abdur Rahman bin Abi Laila. All of them forbade me from this.
