والفطرة: نصف صاع من بر
Translation: The fitrah amount is half a saʿ of wheat.
Burr means wheat. “Half a saʿ” is half of the historical saʿ measure, not half a kilogram. The text will shortly report differing weight interpretations of that measure.
The amount is for each person covered. First determine the number of persons, then multiply by the stated food allowance per person.
