Hasan Basri says: Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) delivered a sermon in the last days of Ramadan and said: O people of Basra! Pay the zakat of your fasts. Hearing this, the people began to look at each other in astonishment. They said: Who among you are the people from Madinah Munawwarah? Stand up and teach your brothers that the Messenger of Allah (peace and blessings be upon him) has made it obligatory to give half a sa’ of wheat and one sa’ each of barley and dates as Sadaqat al-Fitr on every slave and free person, male and female.
