Assalamou aleikoum wa rahmatoullah wa barakatou
The Food of Az-Zakatul-Fitr What is the food that is permissible to give for Zakatul-Fitr?
Answer:
It is reported in the hadith that it is to be given from five things. They are wheat, barley, dried dates , raisins and cottage cheese. However, some of the research scholars have mentioned that specifying these five things was done because they were used at that time. Therefore, they permit giving it from whatever is the common food of the land like rice for example, and corn in the land where it is used as food and so forth.
