The most urgent question is the establishment of true faith (tahqiq ul-iman)

The problem underlying present-day thinking and the troubles
afflicting everyone, no matter what their social status, nation, race
or country, is the lack of a sincere faith in and genuine devotion and
complete submission to Allah. The fact that, with the support of the
theory of evolution, people have gradually turned their backs on faith
in Allah and religious moral values since the 1800s has caused
terrible disasters totake place, one after the other.
Imperialism, which attached no value to people of other nations and
races, regarded them as literally a species of animal and enslaved
themand exploited all their resources, communism that maintained that
war, conflict and bloody revolutions were the only solution that would
supposedly lead mankind to happiness, fascism that evaluated people
according to their skull measurements and regarded other races and
societies as enemies needing to be eliminated, and all such irrational
ideologies that violate good conscience and science have all drawn
strength from Darwinism and literally turned the world into a sea of
blood.
Similarly, it is Darwinism that lies at the root of the erroneous
world view thatindoctrinates people with the idea that nobody should
trust anyone else, that everyone should be suspicious of everyone
else, that allows no one the right to love anyone else and with the
lie that might is right, rather than truth, that human beings are the
result of blind chance and will therefore never have to account for
their actions to anyone.
In essence, the movement of the antichrist is spreading Darwinism and
materialism and keeping them alive by using all thetechnical and
technological means available today. The movement of the antichrist is
inculcating irreligion by the use of newspapers, magazines,
television, radio, movies and the Internet, is using Darwinism as a
supposed scientific foundation to keep irreligion propped up, and has
taken the Islamic world captive and is inflicting huge suffering on
it.
The most important thing to be done in an environment in which the
system of the antichrist is so active is to be instrumental in people
sincerely believing in the existence and oneness of Allah. The
prevalence of true faith, espoused with one's entire conscience, is
the most important way of immediately eliminating all these pains and
troubles. When people genuinely believe, when they genuinely love and
are devoted to Allah, it is obvious that the world will attain the
beauty of Paradise. Because sincere faith means people enjoying
complete love, joy, peace, beauty, quality and nobility. Where there
is certain faith, there will also be art, science, progress, peace and
everything.
That is why the first priority is the intellectual elimination of the
error of Darwinism, which people shelter behind as a superstitious
faith, and to tell people of the countless proofs of the evident
existence of Allah in the finest and most effective manner. In doing
this, however, it is of the greatest importance to adopt a scientific
and rational approach.
Irrational and illogical talk that is unrealistic and insincere will
just have a negative impact on peopleand may turn them even further
away from the religion of Allah. For that reason, it is very important
that in preaching the religion Muslims should make the best use of
their time and opportunities, be instrumental in people coming to love
and fear Allah rather than talking about matters they can easily learn
from catechisms, Islamic law books and other religious texts, and
telling them things that will enable them to realize the joy that
comes from living for.A Muslim must possess theculture and knowledge
with which to smash the idol of denial, Darwinism, by making the most
rational use of the opportunities offered by science. He must possess
a knowledge of all branches of science and know how to make the most
productive use of them forthe religion of Allah. He must be able to
describe the proofs of the existenceof Allah in the wisest, most
memorable, most impressive and finest manner, by using all the
technological means at hisdisposal.
At a time when lack of faith is inflicting terrible disasters on
mankind, it is irrational to spend time and opportunities on matters
that are not urgent instead of first being instrumental in people
either coming to faith or strengthening the faith that they already
have.
