Muḥammad b. Mūsā b. al-Mutawakkil رضي الله عنه narrated to us, saying that Muḥammad b. Abī ʿAbd Allāh al-Kūfī narrated to him among others, from Sahl b. Ziyād, from al-Ḥasan b. ʿAbbās b. Juraysh al-Rāzī, from Abī Jaʿfar (al-Thānī)—Muḥammad b. ʿAlī b. Mūsā b. Jaʿfar b. Muḥammad b. ʿAlī b. al-Ḥusayn b. ʿAlī b. Abī Ṭālib عليهم السلام—from his father, from his grandfather عليهم السلام—i.e., Abū Ibrāhīm al-Kāẓim—who reported that al-Ṣādiq عليه السلام said: “I heard my father saying: “There is not a servant (of Allah) who has read the chapter of ﴾Indeed, We sent it down﴿ a thousand times on Monday and a thousand times on Thursday except that Allāh تبارك وتعالى has created—because of this recitation—an angel called “al-ʿAwī,” whose reach is greater than the seven skies and seven earths. Upon the place of every atom of his body are a thousand hairs, and in each hair a thousand tongues. Every tongue speaks with the vigour of the tongues of the two heavyweights—humans and jinn—thereby seeking forgiveness for the one who recited the chapter, and the Lord تعالى forgives for two thousand years, a thousand times over.”
