الشرح المختصر :

"Zakat al-Fitr" (fast-breaking charity) is an act of worship that Allah, the Almighty, legislated to be performed after completing the Ramadan fast. It is to donate a "sā‘" worth of food from the common local staple food on behalf of the head of the household and each of his Muslim dependents, whether male or female, and young or old. This must be done before the Eid al-Fitr prayer, and it must be given to certain people (such as the poor and needy). It was legislated in order to purify the fasting person from the idle and obscene speech that he has spoken as well as to feed the poor, free them from the need of begging on that day, and make them happy on the day of Eid. "Zakat al-Fitr" is estimated by the majority of scholars one "sā‘" of wheat, barley, dates, or raisins. One "sā‘" equals four medium handfuls, and it was estimated by the Permanent Committee 3 kilograms; or 2600 grams, as stated in the Islamic Researches Magazine.
