It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) took dried curd cheese (aqit) from the people of the desert as Sadaqat al-Fitr.
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is narrated from Abu Sa'id (may Allah be pleased with him) only with this chain; Kathir bin Abdullah is alone in narrating it."
