Be aware that deviating from the path of Islām is in two ways

 *Be aware that deviating from the path of Islām is in two ways:*

واعلم أن الخروج من الطريق على وجهين؛

*One of them is when a man deviates from the path but with a desire of truth (in his deviation), such will never be followed upon his deviation because he is destroyed.*

أما أحدهما: فرجل زل عن الطريق، وهو لا يريد إلا الخير، فلا يُقتدى بزلته، فإنه هالك،

*The other is he who antagonizes the truth and opposes those who have gone before him among the pious (scholars), such should be regarded as astray as ḍāl muḍīl (ie: well as leading others astray);*

وآخر عاند الحق وخالف من كان قبله من المتقين، فهو ضال مضل

*He is also a block-headed devil for this ummah.*

 شيطان مريد في هذه الأمة،

*It is proper for whoever knows his affairs that he should warn the people (Muslims) about him, and that he reveal his matter to them lest someone should unknowingly fall into his heresies.*.

حقيق على من يعرفه أن يحذر الناس منه، ويبين لهم قصته؛ لئلا يقع أحد في بدعته فيهلك.
