قَالَ مَالِك : وَلَا أَرَى ذَلِكَ وَاجِبًا ، وَأَحَبُّ إِلَيَّ أَنْ يَفْعَلَهُ إِذَا كَانَ قَوِيًّا عَلَيْهِ ، فَمَنْ فَدَى فَإِنَّمَا يُطْعِمُ مَكَانَ كُلِّ يَوْمٍ مُدًّا بِمُدِّ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ
Imam Malik, may Allah have mercy on him, said: In my view, paying fidya is not obligatory except for the one who has the ability to pay it; for such a person, it is better to give it. Whoever gives fidya should give one mudd of food for each fast, according to the mudd of the Messenger of Allah, peace and blessings be upon him.
