Chapter on Time of Zakat

And from him, from Ahmad ibn Muhammad, from Abd al-Rahman ibn Abi Najran and Ali ibn al-Hasan al-Tawil, from Safwan ibn Yahya, from Is ibn al-Qasim, from Abu Abdillah عليه السلام, peace be upon him: Imam عليه السلام said: “Regarding zakat, whatever Banu Umayyah have taken from you, count it as such (zakat). And do not give them anything as much as you are able, for wealth cannot remain such that it is paid as zakat twice.”
