It is permissible, rather, it is obligatory to speak about the people of innovation and to warn against them and their innovation, individually or as a group. [This includes] those from the past as well as the present, from the Khawārij, the Rawāfiḍ, the Jahmiyyah, the Murjī’ah, the Karāmiyyah, and the people of kalām (theological rhetoric) — those who the knowledge of kalām has dragged them to corrupt beliefs like negation of [all of] Allāh’s attributes or some of them. So, it is obligatory to warn against them and their books; likewise, whoever traverses upon their [deviated] methodology from the present-day sects or groups, and from those who outwardly profess tawḥīd and the sunnah. It is obligatory to have opposition to them and to avoid their methodologies. Rather, one must wage war against them and flee from them and their people. Included amongst them are those who aid them, defend them, mention their good qualities, praise them, and praise their personalities and leaders,1 and show preference for their methodology over the methodology of the people of tawḥīd, the Sunnah, and the Jamāʿah.
 This is if their condition and that which they have with them from opposition to the Sunnah is known.
