Muslim ibn Shubah said: Nafi ibn Alqamah appointed my father as charge d'affaires of his tribe, and commanded him to collect sadaqah (zakat) from them. My father sent me to a group of them; so I came to an aged man called Sa'r ibn Disam I said: My father has sent me to you to collect zakat from you. He asked: What kind of animals will you take, my nephew? I replied: We shall select the sheep and examine their udders. He said: My nephew, I shall narrate a tradition to you. I lived on one of these steppes during the time of the Messenger of Allah ﷺ along with my sheep. Two people riding a camel came to me. They said to me: We are messengers of the Messenger of Allah ﷺ, sent to you so that you may pay the sadaqah (zakat) on your sheep. I asked: What is due from me for them? They said: One goat. I went to a goat which I knew was full of milk and fat, and I brought it to them. They said: This is a pregnant goat. The Messenger of Allah ﷺ prohibited us to accept a pregnant goat. I asked: What will you take then? They said: A goat in its second year or a goat in its third year. I then went to a goat which had not given birth to any kid, but it was going to do so. I brought it to them. They said: Give it to us. They took it on the camel and went away. Abu Dawud said: Abu Asim transmitted this tradition from Zakariyya. He said: Muslim bin Shubah is a narrator in the chain of this tradition as reported by the narrator Rawh.
