صدقة الفطر واجبة على الحر المسلم إذا كان مالكا لمقدار النصاب
Translation: Fitrah is obligatory upon a free Muslim who owns wealth equal to the nisab.
The text attaches liability to being Muslim, free in the historical legal framework, and possessing the relevant nisab. It describes a legal obligation, not simply a voluntary Eid gift.
The following clause qualifies the property test: essential personal needs are excluded before determining the relevant surplus.
