Mishkat al-Masabih
He said that God’s messenger prescribed the zakat relating to the breaking of the fast as a purification of the fasting from empty and obscene talk and as food for the poor. Abu Dawud transmitted it.
وَعَن ابْنِ عَبَّاسٍ قَالَ: فَرَضَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ زَكَاةَ الْفِطْرِ طُهْرَ الصِّيَامِ مِنَ اللَّغْوِ وَالرَّفَثِ وَطُعْمَةً لِلْمَسَاكِينِ. رَوَاهُ أَبُو دَاوُد
