Fitrah for a person is given on a weight of three kilograms (one sa`a) on any food commodity like wheat, barley, rice, millet, raisins or dates.
Ayatullah Seestani is of the opinion that the item that is not a staple food in your town should not be given in Fitrah.
Say, for example, if millet is not a staple in Vancouver then Vacouver mumineen should not pay Fitrah on millet.
