A number of our people have narrated from Sahl ibn Ziyad from Yusuf al-Sukht from Hamdan ibn al-Nadr from Muhammad ibn ‘Abd Allah al-Sayqal who has said the following: “Abu al-Hassan, meaning al-Rida (a.s.), once came out to us on the twenty-fifth day of the month of Dhul Qa’dah and said, ‘Fast, for today I have awoken while fasting.’ We then said, ‘May we be sacrificed for you, which day is it?’ He replied, ‘It is the day during which the mercy (of Allah) was spread, the earth was extended, al-Ka‘bah was placed in it, and Adam (AS) descended therein.’” ضعيف - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (16/366))
