Al-Infiṭār: Merits
Al-Hasan ibn Abī al-ʿAlā reports from Imam al-Ṣādiq (a) that: ‘If one recites these two surahs – idhā al-samāʾ infaṭarat [82] and idhā al-samāʾ inshaqqat [84] – constantly, in obligatory and optional prayers, there will be none to veil or prevent him from God, and he will continue gazing towards God [i.e. remain in His presence] whilst he gazes towards Him, until humankind is done from the accounting [on the Day of Resurrection].’1
Makārim Shīrāzī, after quoting the above tradition, remarks that this applies: ‘For one who places them [i.e. the two surahs] in the deepest regions of his soul, and constructs his self and his actions on their foundation; and not for one who merely recites them with the tongue.’2
