Chapter 37 | The Case of Seniors Who Feel Weak when Fasting
4ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ مَحْبُوبٍ عَنِ الْعَلاءِ بْنِ رَزِينٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ قَالَ سَمِعْتُ أَبَا جَعْفَرٍ (عَلَيْهِ السَّلاَم) يَقُولُ الشَّيْخُ الْكَبِيرُ وَالَّذِي بِهِ الْعُطَاشُ لا حَرَجَ عَلَيْهِمَا أَنْ يُفْطِرَا فِي شَهْرِ رَمَضَانَ وَيَتَصَدَّقُ كُلُّ وَاحِدٍ مِنْهُمَا فِي كُلِّ يَوْمٍ بِمُدٍّ مِنْ طَعَامٍ وَلا قَضَاءَ عَلَيْهِمَا فَإِنْ لَمْ يَقْدِرَا فَلا شَيْءَ عَلَيْهِمَا.
4. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from al-Hassan ibn Mahbub from al-‘Ala’ ibn Razin from Muhammad ibn Muslim who has said the following: “I once heard abu Ja‘far , say, ‘An old man and one who suffers from thirst have permission not to fast in the month of Ramadan, and instead each one pays a ransom of one mud of food for every day, and thereafter they are not obligated for any Qada’ (compensatory fast). If they cannot afford, they are not obligated for anything.’”
