(4) Abdul Wahid bin Abdullah bin Younus narrated from Ahmad bin Muhammad bin Rabah az-Zuhri from Ahmad bin Ali al-Himyari from al-Hasan bin Ayyoob from Abdul Kareem bin Amr al-Khath’ami that Jama’a as-Sa’igh had said: “I heard al-Mufadhdhal bin Umar asking Abu Abdullah as-Sadiq : “Does Allah impose (upon people) to obey someone and then the divine revelation keeps that secret?” Abu Abdullah as-Sadiq said: “Allah is more glorified, merciful and kinder to His people than to impose upon them obeying someone but the divine revelation keeps that secret day and night.” Then his son Abul Hasan Musa appeared. Abu Abdullah as-Sadiq said to al-Mufadhdhal: “Would you like to look at the keeper of Imam Ali’s book?” Al-Mufadhdhal said: “And is there anything else that makes me more delighted than this?!” Abu Abdullah as-Sadiq said: “This is the keeper of Ali’s hidden book, about which Allah has said, ‘None shall touch it save the purified ones.’”
