We know indeed that it grieves you: this is a reprimand to the Messenger of God for the manifestation of his soul by means of grief; they do not deny you, to the end [of the verse]: that is, their denial is not a denial of you, since in this summoning you do not subsist by means of your own soul, nor is this speech an attribute of yours. Rather you summon them by means of God and His attributes: this is an established habit [of God].
