Merits of the Month of Ramaḍān

My father رضي الله عنه narrated to us, saying that Saʿd b. ʿAbd Allāh narrated to him among others, from Muḥammad b. al-Ḥusayn b. Abī’l-Khaṭṭāb, from Muḥammad b. ʿAbd Allāh b. Mihrān, from Ṣāliḥ b. ʿUqba, from al-Mufaḍḍal b. ʿUmar, who said: “Abū ʿAbd Allāh al-Ṣādiq عليه السلام mentioned the chapter of ﴾Indeed, We sent it down﴿ and then said: “Is there anything (more) to clarify about its superiority in virtue over other chapters?” Al-Mufaḍḍal reports: “I said: “And what is that thing due to which it is superior in virtue?” So he replied: “The guardianship of Amīr al-Muʾminīn عليه السلام was revealed in it.” I retorted: “In the Night of Power which we anticipate in (the month of) Ramaḍān?” He continued: “It is the night in which the heavens and the earth were determined.”
