(20) باب كَمْ يُؤَدَّى فِي صَدَقَةِ الْفِطْرِ
Abd' Allah b. Umar said :
The Messenger of Allah(ﷺ)prescribed the sadaqah at the end of Ramadan one sa'. The narrator then transmitted the tradition like the one narrated by Malik. This version adds : "Young and old. He gave command that this should be paid before the people went out to prayers."Abu Dawud said : 'Abd Allah al-'Umari narrated it from Nafi' through his chain : "on every Muslim." The version of Sa'id al-Jumahi has : "Among the Muslims." The well-known version transmitted by 'Ubaid Allah does not mention the words "among the Muslims"
