prohibited acts in Islam that lead to division and cause hatred

Islam vehemently has denounced and
condemned the following acts and strictly
prohibited their practice. This is to
promote peace and security in the
society, and to eradicate or curtail
wrath, hatred, greed, and resentment
which are the root causes of conflicts and
violence.
POLYTHEISM AND
IDOLATRY
Polytheism and idolatry inevitably cause
conflict as people compete and vie for
recognition, status, dominance and tribute
for their idols and associated ideologies
and mythologies. If all people worshipped
the one and only God, then the greatest
root of violence would be eradicated.

Allah said:
"And ask those We sent before you of Our
messengers; have We made besides the Most
Merciful deities to be worshipped?" (43:45)
Allah, the Most Glorious, said:
"And We did not send a messenger before
you, except that We revealed to him that
there is no god worthy of worship except
Me, so worship Me." (21:25)
Allah, the Most Almighty and Majestic,
said:
"And verily, We have sent among every
community a Messenger proclaiming, 'Worship
Allah (alone), and avoid all false gods.'" (16:36)

02 SORCERY.
This prohibition is based on the numerous
evidences like the saying of Allah:
"But neither of these two taught anyone
[sorcery] till they had said, 'Truly, we are a trial,
so do not disbelieve.'" (2:102)
And in the hadith of Allah's Messenger ¿¿¿¿:
"Avoid the seven destructive sins." People
inquired, "O Prophet of Allah! What are
these destructive sins?" He said, "They are:
associating others in the worship of Allah,
sorcery, killing an innocent soul without any
legitimate reason, dealing with usury,
the battlefield, falsely accusing innocent
female believers with fornication, adultery,
or moral corruption." (Bukhari & Muslim)
