"Now, whenever thou meet such as indulge in [blasphemous] talk about Our messages, turn thy back upon them until they begin to talk of other things and if Satan should ever cause thee to forget [thyself], remain not, after recollection, in the company of such evildoing folk, for whom those who are conscious of God are in no wise accountable. Theirs, however, is the duty to admonish [the sinners], so that they might become conscious of God."
