٩ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنِ ابْنِ فَضَّالٍ عَنِ ابْنِ بُكَيْرٍ عَنْ زُرَارَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) عَنْ أَفْضَلِ مَا جَرَتْ بِهِ السُّنَّةُ فِي التَّطَوُّعِ مِنَ الصَّوْمِ فَقَالَ ثَلاثَةُ أَيَّامٍ فِي كُلِّ شَهْرٍ الْخَمِيسُ فِي أَوَّلِ الشَّهْرِ وَالأَرْبِعَاءُ فِي وَسَطِ الشَّهْرِ وَالْخَمِيسُ فِي آخِرِ الشَّهْرِ قَالَ قُلْتُ لَهُ هَذَا جَمِيعُ مَا جَرَتْ بِهِ السُّنَّةُ فِي الصَّوْمِ فَقَالَ نَعَمْ.
9. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Faddal from ibn Bukayr from Zurarah who has said the following: ’’Once I asked abu ‘Abd Allah , about the best tradition in optional fasting. The Imam replied, ‘It is three days of fasting every month. It is the first Thursday, the Wednesday after the tenth day and the last Thursday of a month.’ I then asked, ‘Is that all of the tradition about fasting?’ He replied, ‘Yes, this is all about it.’”
