Muwatta Malik, Book 22, Hadith 1026 (In-Book) ⓘ

Yahya related to me from Malik from Yahya ibn Said that Sulayman ibn Yasar said, "I understood from people that when they made the kaffara for a broken oath, they gave a mudd of wheat according to the smaller mudd. They thought that that would compensate for them." Malik said, "The best of what I have heard about the one who does kaffara for breaking his oath by clothing people is that if he clothes men he clothes them each in one garment. If he clothes women, he clothes them each in two garments, a long shift and a long scarf, because that is what is satisfactory for each of them in the prayer."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، أَنَّهُ قَالَ أَدْرَكْتُ النَّاسَ وَهُمْ إِذَا أَعْطَوْا فِي كَفَّارَةِ الْيَمِينِ أَعْطَوْا مُدًّا مِنْ حِنْطَةٍ بِالْمُدِّ الأَصْغَرِ وَرَأَوْا ذَلِكَ مُجْزِئًا عَنْهُمْ ‏.‏ قَالَ مَالِكٌ أَحْسَنُ مَا سَمِعْتُ فِي الَّذِي يُكَفِّرُ عَنْ يَمِينِهِ بِالْكِسْوَةِ أَنَّهُ إِنْ كَسَا الرِّجَالَ كَسَاهُمْ ثَوْبًا ثَوْبًا وَإِنْ كَسَا النِّسَاءَ كَسَاهُنَّ ثَوْبَيْنِ ثَوْبَيْنِ دِرْعًا وَخِمَارًا وَذَلِكَ أَدْنَى مَا يُجْزِي كُلاًّ فِي صَلاَتِهِ ‏.‏
