Hadith: Arabic Text followed by English Translation.
عن ابن عمر رضي الله عنهما قال
فرض رسول الله صلى الله عليه وسلم زكاة الفطر صاعاً من تمر أو صاعاً من شعير، على العبد والحر والذكر والأنثى والصغير والكبير من المسلمين، وأمر بها أن تؤدى قبل خروج الناس إلى الصلاة
البخاري ١٥٠٣
Ibn ‘Umar (may Allaah be pleased with him) said:
The Messenger of Allaah (peace and blessings of Allaah be upon him) enjoined zakaat al-fitr, a saa’* of dates, or a saa’ of barley, upon all the Muslims, slave and free, male and female, young and old, and he commanded that it be paid before the people went out to pray.
Narrated by Bukhari, 1503
*What is meant by a saa’ here is the saa’ of the Messenger of Allaah (peace and blessings of Allaah be upon him), which is four times the amount that may be held in the two hands of a man of average build.
