ما هي حقيقة الحب والبغض في الله (حب المسلمين وبغض من لا يدين بدين الحق) وما هي الأدلة الشرعية على ذلك؟

Love for Allah is the believer's love [for others] for the sake of their religion and their obedience to Allah, and hatred for the disobedient commensurate with their disobedience, and hatred for the disbelievers.

Whoever loves a servant and loves him for no other reason than for Allah's sake, and whoever dislikes returning to disbelief after Allah has saved him from it, just as he dislikes being cast into the fire; he has found the sweetness of faith.

The reality of love for Allah is that it does not increase with kindness nor decrease with harshness, and that the love is purely for Allah the Almighty, and that one loves for the sake of Allah's pleasure, and loves for people what he loves for himself and dislikes for them what he dislikes for himself.

Whoever loves for Allah's sake, hates for Allah's sake, gives for Allah's sake, and withholds for Allah's sake, has perfected his faith.

The best of faith is that you love for Allah's sake and hate for Allah's sake, and that you engage your tongue in the remembrance of Allah the Almighty, and that you love for people what you love for yourself and dislike for them what you dislike for yourself, and that you speak good or remain silent.
