Muhammad ibn ‘Isma‘il has narrated from al-Fadl ibn Shadhan from Safwan ibn Yahya and Ibn Abi ‘Umayr from ‘Abd al-Rahman ibn al-Hajjaj who has said the following: “I once asked abu al-Hassan عليه السلام, about the case of the two days after al-Fitr; if fasting is permissible therein. He (the Imam) said, ‘I do not like for you to fast on those days.’”
