1. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ‘Uthman ibn ‘Isa from Sama‘ah who has said the following: “I once asked him (the Imam) عليه السلام, about fasting on the day of al-Fitr (first day of the month of Shawwal). He (the Imam) said, ‘No, it is not proper to fast as well as on the days of al- Tashriq.’”
