186. hadíth
وَ سَأَلَ عَبْدُ اَلْمَلِكِ بْنُ عُتْبَةَ اَلْهَاشِمِيُّ أَبَا اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ: عَنِ اَلشَّيْخِ اَلْكَبِيرِ وَ اَلْعَجُوزِ اَلْكَبِيرَةِ اَلَّتِي تَضْعُفُ عَنِ اَلصَّوْمِ فِي شَهْرِ رَمَضَانَ قَالَ «يَتَصَدَّقُ عَنْ كُلِّ يَوْمٍ بِمُدٍّ مِنْ حِنْطَةٍ».
Abd al-Malik ibn Utbah al-Hashimi asked Abu al-Hasan (a.s) about an elderly man and an elderly woman who are too weak to fast during the Month of Ramadan. Imam (a.s) said: "They should give a mudd (a specific measure) of wheat as charity for each day."
