مُوَطَّأُ مَالِكٍ
Muwatta Malik 1856
Sadaqa
حَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ لاَ تَحِلُّ الصَّدَقَةُ لآلِ مُحَمَّدٍ إِنَّمَا هِيَ أَوْسَاخُ النَّاسِ .
Yahya related to me from Malik that he heard that the Messenger of Allah, (ﷺ), said, "Sadaqa to the family of Muhammad is not halal. It is only people's impurities."
