Discussion of the phrase "religion is opium of the nations
This phrase is for Karl Marx ( the founder of the Communism philosophy ) but his speech is wrong because the opium is an anesthetic material while the religion is not for the following reasons
First : the religion urges to the emotion through spreading the
justice and mercy in all the world in order to save them
from the injustice which they suffered from it for along
time
Second : finding the emotion that is opposite to the injustice and unjust people in all societies
Third : it put laws opposite to the injustice some of them are
obliged and some are forbidden , it prevented the
person from attacking the others & deny their rights
indeed Allah decrees the commands of justice and
kindness, and of giving to relatives , and forbids from
the shameful and evil and rebellion ; He advises you so
that you may pay heed ) Surah Al-Nahl ( the bees

Fourth : we see both Communist & capital doctrines had
scared from the revolution of the oppressed people
and their liberty so they made some measures to
prevent such things , the communist and radical
countries used the policy of torturing , repressing and
frightening while the capital countries distracted their
people with money economic problems and sport and
licentious programs ….etc. , all these things made the
nations unaware for their real problems and basic
woes
While we don't find these things in the holy religion because these things are forbidden in the religion of our prophet Mohammed
But some who belong to Islamic religion have ideas contradict the speech mentioned above like Sufism doctrine but there are laws in our religion refute their idea
