The Meaning of Hatred and Dislike
Bughd linguistically: is the opposite of love. Allah made one hated to the people (baghghadah) so they hated him (abghaduh). Baghda’ is the intense form of bughd (hatred). Tabaghada al-qawm is said when a people hate one another.  al-Mukhassas, Ibn Sidah (4/84); al-Misbah al-Munir, al-Fayyumi (1/56).
Bughd technically: is repulsion from the thing that is sought, and it is the opposite of love.  al-Tawqif `ala Muimmat al-Ta`rif, al-Manawi (p. 81).
Karahiyah linguistically: is the opposite of satisfaction and liking. It is said: karihtu al-shay’a karahatan wa karahiyatan (I disliked a thing a great dislike). Kurh - with a dammah - is difficulty. Karrahtu ilayhi al-shay’a takriha (I made something disliked to him a dislike) is the opposite of making something liked to another.  al-Sihah, al-Jawhari (6/2247); Maqayis al-Lughah, Ibn Faris (5/173).
Karahiyah technically: what is disliked is the opposite of what is beloved, taken from karah (dislike) that is the opposite of mahabbah (like, love).  al-Kuliyyat, al-Kafawi (p. 1408). The Difference between Dislike, Hatred, Desistance (Iba’), and Repulsion (Nufur al-Tab`)  al-Furuq al-Lughawiyyah, al-`Askari (p. 8, 104, 451).
Desistance is refusal, and one may dislike that which he is unable to desist from. Hatred may expand that which dislike cannot expand. It is, for example, said: ubghidu zayda (I hate Zayd), meaning: I hate to honour and benefit him. It is not said: akrahuh (I dislike him) in that same meaning. Nonetheless, dislike may be used in that which hatred is not used, such that, for example, it is said: akrahu hadha al-ta`am (I dislike this food) but ubghiduh (I hate it) is not used.
Unwillingness the other usage of karahah is the opposite of willingness, while repulsion is the opposite of desire. Man may willingly drink bitter medicine despite being repulsed by it, and if repulsion were the same as unwillingness it would have been impossible to simultaneously take place with willingness.Prohibition of Hatred and Dislike in the Qur’an and Sunnah

❖ al-Zubayr ibn al-`Awwam, Allah be pleased with him, narrated that the Prophet ﷺ said: “The disease of the nations before you is creeping towards you: envy and hatred, it is the cutter. I do not say that it cuts the hair, but it severs religiosity. By the One in Whose Hand is my soul, you will not enter the Garden until you believe, and you will not believe until you love each other. Shall I tell you about what will strengthen that for you? Spread greetings of peace among each other.”  Reported by al-Tirmidhi (2510) and Ahmad (1412). al-Tirmidhi said: “They differed in its narrations.” al-Mundhari graded its chain as good in al-Targhib wa al-Tarhib (4/31) and likewise al-Haytami in Jami` al-Zawa’id (8/33). al-Albani graded it as sound in Sahih Sunan al-Tirmidhi (2510).
