The Messenger of Allah ﷺ said, "There are three qualities, whoever possesses them will taste the sweetness of faith. That Allah and His Messenger are more beloved to him than anything else, that he loves a person solely for the sake of Allah, and that he hates returning to disbelief after Allah has rescued him from it just as he hates being thrown into the Fire."
حدثنا ابن أبي عمر حدثنا عبد الوهاب عن أيوب عن أبي قلابة
أن رسول الله ﷺ قال ثلاث من كن فيه وجد بهن طعم الإيمان من كان الله ورسوله أحب إليه مما سواهما وأن يحب المرء لا يحبه إلا لله وأن يكره أن يعود في الكفر بعد إذ أنقذه الله منه كما يكره أن يقذف في النار
