We, on behalf of young or old, free or slave, used to take out the
Zakat of Fitr while the Messenger of Allah (ﷺ) was among us, in three kinds, one sa' of dates, one sa' of cheese, or one sa' of barley, and we continued to take that out till the time of Mu'awiya, for he saw that two mudds of wheat were equal to one sa' of dates. Abu Sa'id sald: I would continue to take that out as before (i e. one sa' of wheat).
