تفسير : (and he is not) i.e. muhammad (pbuh) (avid of the unseen) he is accused with regard to the revelation; and it is also said this means: he is not avaricious.
Jalāl al-Dīn al-Maḥallī
تفسير : and he, muhammad (s), is not to be accused of [knowing] the unseen, what is hidden of the revelation and the tidings of the heaven (a variant reading [for bi-zanīnin] has bi-danīnin, meaning that he is not ‘niggardly’ [with the unseen] so as to reduce something of it [and not disclose it]).
