The Shaykh (may Allah have mercy upon him) said:

Fifth: Whoever harbors hatred for anything that the Messenger ﷺ has brought—even if he outwardly practices it—has committed disbelief.

In truth, this is a kind of hypocrisy, for hatred is an inward act of the heart. What is meant here is that he despises it with a religious, rational aversion, deeming it ugly and detestable; this necessarily leads him to hate anyone who calls to it. An example would be a person who loathes the prayer (ṣalāh). Such a person sees no virtue or benefit in it and regards its motions—standing, bowing, and prostrating—as foolishness and ignorance, so he detests the prayer, and that detestation extends to those who perform it.

By contrast, the one who believes in Allah and His Messenger affirms that the legislation of prayer is a truth from Allah, that performing it earns reward, and that he loves to establish it. Yet he may find it hard to rise for the prayer and therefore dislikes getting up—a natural dislike. He does not, however, give in to this aversion; rather, he resists his own whim. This is a different matter altogether and is not what we are discussing, for this is a natural dislike that is countered by the love born of faith. Jihād, likewise, is naturally burdensome to the soul, as the Exalted says: “Fighting has been prescribed for you, though it is hateful to you” (al-Baqarah 2:216). Man by nature dislikes death and shuns jihād because of the hardship and risk to life it entails, but when faith in Allah, and belief in the merit of jihād and martyrdom in the path of Allah, become sound and strong, the bitter turns sweet; and for this reason
