Book: The Chapters Regarding Zakat
Narrator(s): Aabad bin Y'aqub al-Rwajny عباد بن يعقوب الرواجني, Abdullah ibn Ja'far, Ali ibn Abi Talib, Isma'il bin 'Abdullah bin Ja'far إسماعيل بن عبد الله بن جعفر بن أبي طالب

Suwaid bin Ghafalah said: ”The Zakah collector of the Prophet came to us, and I took him by the hand and read in his order: ‘Do not gather separate herds and do not separate herd for fear of Sadaqah’. A man brought him a huge, fat she-camel, but he refused to accept it. So he brought him another of lower quality and he accepted it. He said: ‘What land would shelter me, if I came to the Messenger of Allah having taken the nest of a Muslim man’s camels?’ ”
