Sunan Abi Dawud, 1614

Rapporté par Abdullah ibn Umar : À l’époque du Messager d’Allah ﷺ, les gens donnaient la sadaqa à la fin du Ramadan, à la rupture du jeûne, un sa’ d’orge sans paille, ou de raisins secs. Abdullah a dit : Quand Omar رضي الله عنه lui a succédé et que le blé est devenu abondant, Omar a prescrit un demi-sa’ de blé à la place de ces choses

Narrated Abdullah ibn Umar: The people during the lifetime of the Messenger of Allah (ﷺ) used to bring forth the sadaqah at the end of Ramadan when closing the fast one sa' of barley whose straw is removed, or of raisins. Abdullah said: When Umar (Allah be pleased with him) succeeded, and the wheat became abundant, Umar prescribed half a sa' of wheat instead of all these things
