Ibn Sirin محمد بن سيرين الأنصاري · The Book of Zakah

"The Messenger of Allah came out with a stick in his hand, and a man had hung up a bunch of dry and bad dates. He started hitting that bunch of dates and said: 'I wish that the one who gave this Sadaqah had given something better than this, for the one who gave these dry, bad dates will eat dry, bad dates on the Day of Resurrection."'

"The Messenger of Allah enjoined Zakatul-Fitr, a Sa' of dates or a Sa of barley, upon the free person and the slave, male and female, young and old, among the Muslims. He commanded that it be given before the people went out to the ('fd) prayer."
