It is narrated from Hazrat Ubayy bin Ka'b (may Allah be pleased with him) that once the Noble Prophet (peace and blessings be upon him) sent me to collect zakat from Baliy, 'Uzrah, and all the Banu Sa'd bin Hudhaym. I collected zakat from them and came to the last man. His house and area in Madinah Munawwarah were closer to the house of the Noble Prophet (peace and blessings be upon him) than anyone else's. When he presented all his wealth before me, his zakat amounted to only one bint makhad (a young she-camel). I informed him that this was the amount of zakat due from him. He said, "This she-camel neither gives milk nor is it fit for riding. By Allah! Never before has the Noble Prophet (peace and blessings be upon him) or any of his messengers come and stood over my wealth. Now, I cannot give Allah such an animal from my wealth as a loan which neither gives milk nor is fit for riding. However, here is a young and healthy she-camel; take it." I said, "I cannot take anything for which I do not have permission. However, the Noble Prophet (peace and blessings be upon him) is very near to you. If you wish, you may go to him and present the same offer you made to me. If he accepts it, very good; otherwise, he will return it to you." He said, "I will do just that." So he set out with me and took along the she-camel he had offered me, until we reached the presence of the Noble Prophet (peace and blessings be upon him). He said, "O Messenger of Allah! Your messenger came to collect zakat from my wealth. By Allah, never before has the Noble Prophet (peace and blessings be upon him) or any of his messengers come and stood over my wealth. So I gathered all my wealth. The messenger thought that one bint makhad was due from me, but that she-camel neither gave milk nor was fit for riding. Therefore, I presented a young and healthy she-camel before him, but he refused to take it. Now, O Messenger of Allah! I have brought it to you; please accept it." The Noble Prophet (peace and blessings be upon him) said, "Only this much zakat was due from you, but if you wish to do good voluntarily, we will accept it. Allah will reward you for it." He presented the she-camel, and the Noble Prophet (peace and blessings be upon him) ordered it to be accepted and prayed for blessings in his wealth.
