4. Muhammad ibn Musa ibn al-Mutawakkiil said: Muhammad ibn Ja’far al-Asadi said, that Musa ibn `Imran al-Nakha`I said, on the authority of his uncle al-Husayn ibn Yazid l-Nawfili, on the authority of Muhammad ibn Sinan, on the authority of al-Mufaddal ibn Umar that abu 'Abdillah said: “Verily, Allah, Blessed and Exalted be He, has given the believer a guarantee.” I asked, “What is it?” He replied, “If a believer professes his (Allah’s) divinity, Muhammad’s ﷺ prophethood, and `Ali’s Imamate, and carries out his duties, He guarantees him eternal life in His Presence [jiwar].” I said: “By Allah! This is a blessing with which none of the blessings bestowed upon the children of Adam can compare!” Abu 'Abdillah replied, “Do little, and you will enjoy much.”
