Musannaf Ibn Abi Shaybah 10737 — Those who disliked goods as zakah

Ibn Jurayj said: I heard Ibn Abi Najih say that Umar bin Abd al-Aziz wrote concerning the zakah of dates: the zakah of Barni dates (a particular variety) is to be paid in Barni dates, and the zakah of Lawn dates (a particular variety) in those same dates; Lawn dates are not to be taken as the zakah of Barni dates.
