تفسير : (of the jinn and of mankind) he says: satan whispers in the hearts of the jinn just as he whispers in the hearts of mankind. the last two surah were revealed about labid ibn al-a'sam, the jew, who used black magic on the prophet (pbuh) and when the prophet (pbuh) read these two surahs on labid's black magic, allah relieved him from it and it was as if he was untied from his fetters'.
Jalāl al-Dīn al-Maḥallī
تفسير : of the jinn and mankind’ (mina’l-jinnati wa’l-nāsi: an explication for the whispering satan being of the jinn and [also] of the humans, similar to god’s saying, the devils of humans and jinn [q. 6:112]; or, mina’l-jinnati, ‘of the jinn’, is an explication for him [satan], wa’l-nāsi, ‘and [of] mankind’ being a supplement to al-waswās, ‘the whisperer’). both [explanations] apply to the evil of the mentioned labīd and his daughters; the objection to the first opinion is that humans do not ‘whisper’ in the hearts of [other] humans, but that it is the jinn who whisper in their hearts: i would respond by saying that human beings also ‘whisper’ in a manner appropriate to them, [beginning] externally, whereafter their whispers reach the heart and establish themselves in it in the way in which this [customarily] happens. but god knows best what is correct, and to him shall be the return and the final destination, and may god bless our master muhammad and his family and companions, and grant [them all] much peace, forever and always. god suffices for us and [what] an excellent guardian [is he]! and there is no power or might except in god, the sublime, the tremendous.
