4. [4/-] al-Tahdhib: Sa’d b. Abdallah from Ahmad b. Muhammad from al-Husayn b. Sa’id from Hammad b. Isa from Umar b. Udhayna from Zurara who said: I was seated at Abi Ja’far’s عليه السلام place and there was no one with him except his son Ja’far, so he (Abu Ja’far) said:

O Zurara, Abu Dhar رضي الله عنه and Uthman argued in the life-time of the prophet, so Uthman said: every kind wealth whether it be gold or silver which circulates [is active i.e. having in-flow and out-flow], is worked with [as a capital], and is used for business – then there is Zakat on it if a year elapses, so Abu Dhar رضي الله عنه said: as for that which is used for business, is active, and is worked with – then there is no Zakat on it, rather Zakat is on that which is buried treasure (found fortuitously) and also on stored-up (saved) wealth, so if a year elapses on it then on it is Zakat, so they argued and referred it back to the messenger of Allah صلى الله عليه وآله, so he said: the true position is what was said by Abu Dhar, so Abu Abdillah عليه السلام said to his father: you do not want anything else but that such a one [narration] comes out [and is spread among the people] so that the people stop giving their poor and needy (anything of Zakat)?! So his father said: keep to yourself [don’t interfere], I do not find any option other than it (to narrate what happened and speak the truth).
