Muḥammad b. Yaḥyā al-ʿAṭṭār said: “Jaʿfar b. Muḥammad b. Mālik al-Fazārī al-Kūfī narrated to us, from Isḥāq b. Muḥammad al-Ṣayrafī, from Yaḥyā b. al-Muthannā al-ʿAṭṭār, from ʿAbd Allāh b. Bukayr, from ʿUbayd b. Zurāra, who narrated: “I heard Abā ʿAbd Allāh عليه السلام saying: “The people’s Imam will become unaccounted for, whereupon he will attend the pilgrimage season and he will see them, but they will not see him.”
