حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ أَنَسَ بْنَ مَالِكٍ، كَبِرَ حَتَّى كَانَ لاَ يَقْدِرُ عَلَى الصِّيَامِ فَكَانَ يَفْتَدِي . قَالَ مَالِكٌ وَلاَ أَرَى ذَلِكَ وَاجِبًا وَأَحَبُّ إِلَىَّ أَنْ يَفْعَلَهُ إِذَا كَانَ قَوِيًّا عَلَيْهِ فَمَنْ فَدَى فَإِنَّمَا يُطْعِمُ مَكَانَ كُلِّ يَوْمٍ مُدًّا بِمُدِّ النَّبِيِّ صلى الله عليه وسلم .
Yahya related to me from Malik that he had heard that Anas ibnMalik used to pay fidya when he had grown old and could no longermanage to do the fast. Malik said, "I do not consider that todo so is obligatory, but what I like most is that a man does the fastwhen he is strong enough. Whoever pays compensation gives one mudd offood in place of every day, using the mudd of the Prophet, may Allahbless him and grant him peace." Translation Not Available
