Hadith 5:580
It was narrated from Abu Ishaq, who said: Nafi’ narrated to me that Abdullah ibn Umar used to pay Sadaqat al-Fitr on behalf of all the members of his household: their free men and their slaves, their young and their old, and their Muslims and their disbelievers among the slaves.
وروي عن إبي إسحاق قال حدثني نافع أن عبد الله بن عمر كان يخرج صدقة الفطر عن أهل بيته كلهم حرهم وعبدهم صغيرهم وكبيرهم ومسلمهم وكافرهم من الرقيق
