1. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Safwan ibn Yahya and Ali ibn al-Hakam from al-’Ala’ ibn Razin from Muhammad ibn Muslim who has said the following: “I once asked one of the two Imam, (abu Ja’far or abu ‘Abd Allah), ‘Alayhim al-Salam, about fasting on the ninth of Dhul Hajjah (day of ‘Arafah). He (the Imam) said, ‘I do not fast that day. It is the day of imploring and pleading before Allah.”’
