Enam 19:

•  De ki:' Hakikatın en güvenilir şahidi kimdir?'
  'Allah(cc), benimle sizin aranızda en güvenilir şahittir.'
  'Bu Kuran bana, kendisiyle, sizi ve ulaştığı herkesi uyarayım diye bana vahyedildi.'
  '(Size de ulaştığına göre) Allah(cc)'la birlikte başka ilahların olduğuna gerçekten şahitlik eder misiniz?'
  'Ben buna şahitlik etmem!'
  'Tek ilah ancak Allah(cc)'tır. Ve benim, Allah(cc) dışında ilahlık yakıştırdıklarınızla(تُشْرِكُونَ) en küçük bir ilgi ve alakam olamaz, hiç bir bağım da yoktur.'

  and be part of her family. The plural is “ شُرَکَاءُ ” (shuraka’a).
  اشَرَّکَُ “ ” (ash-sharaku): the net of a hunter, the small pathways that emerge from a bigger path “ ”اُمُّ الطَّرِيْقِ
  (ummut tareeq), and end after going some way. Singular is “ شَرَکَۃ ” (sharakah).
  شِرْکٌ “ ” (shirk) is a particular term of the Quran. It means to consider non godly things as Allah’s
  contemporary, or to consider that others also have the same powers as Allah. It can be understood as
  considering man-made laws to be equal to that of Allah’s laws, or to accept the right of others where
  Allah’s right should be acknowledged. The Quran teaches that everything in this universe has been
  subjugated to man and all men are equal. No one has the right to make anyone obey him. As such, there is
  no power higher than man on this earth, i.e. humans are all equal and everything else in the universe is
  subservient to them. Only one being, that is, Allah is above humans. Hence accepting anyone other than
  Allah to be superior to him is an insult to mankind.
  This is what “ شِرْکٌ ” (shirk) is. It makes no difference to Allah’s divinity. Man himself falls from the high
  pedestal of humanness by indulging in “ شِرْکٌ ” (shirk). This is why Quran says that “ شِرْ ک ” (shirk) is the
  greatest crime or sin.
  مُشْرِکِيْنَ “ ” (mushrikeen) are those who fall from man’s stature, and consider others then Allah to be
  superior to them. “ توحيد ” (tauheed) or oneness means the obedience of one Allah’s laws (which He has
  given through the revelation and which are preserved in the Quran) and the conquering of the entire
  universe. Even a little digression in this is considered “ شِرْکٌ ” (shirk).
  universe. Even a little digression in this is considered “ شِرْکٌ ” (shirk).
  اَشْرَکَ “ ” (ashrak): he was guilty of shirk, or of sharing Allah’s place with others.
  مُشْرِکٌ “ ” (mushrik): one who commits shirk. The plurals are “ مُشْرِکُوْنَ ” (mushrikoon) and “ ”مُشْرِکِيْنَ
  (mushrikeen).
  At the time Quran was being revealed, there was one group of people which was claiming to be obedient
  to God’s revelation. These people were called the ones with the book. They are the Jews and Christians.
  The other group was not obedient to any celestial law. They were followers of self-made customs and
  traditions. According to their own concept, they were obedient to Allah but were as well obedient to other
  Gods. These people were called mushrikeen, or those who think Allah’s divinity was also shared by other
  forces. Since both of these groups were deniers of the Quran, they were called kafireen, or the deniers.
  These terms do differentiate between them but the fact is that even those with the book were not really
  obeying Allah’s laws, but were actually following man made laws. They followed the religion given to
  them by their religious scholars. The laws of Allah in their real shape were no longer with them at all, and
  whatever they had was also a formality. Their deeds or acts were dependent on the writ of the scholars.
  As such, in deed they too were mushrikeen, as the Quran calls them in 2:135:
  Deen of oneness is the right path, and the different sects are those small pathways which mislead man to
  other directions and meet a dead end after going some way. That is why the Quran has called sectarianism
  as shirk in 30:31-32, because in sects the last authorities are human beings and not Allah. In Deen, any
  argument or the last word belongs to Allah’s laws only.
  As such shirk not only means to worship idols and statues, it is also means to give man-made laws the
  status of Allah’s law (and this is big shirk). In this way they divide God’s Deen into different sects.
  The Quran says that those who do this call themselves Momin, but in fact are mushrik.
  Just as Quran discusses one-ness or unity of Allah all through the book, it also discusses shirk and its
  elements. The Quran’s basic teaching is to obliterate shirk and establish oneness.
  لَا اِلٰہَ اِلَّا للهُ“ ” (la ilaha illal lah) is aimed towards this meaning. That is, denial or refusal to obey any law
  except Allah’s law and to accept Allah’s law whole-heartedly and practically. Muslims and mushriks are
  opposites of one another (3:63), and the believers on non-godly forces and the acceptors of devilish
  authority are “ مُشْرِکِيْنَ ” (mushrikeen) (16:99-100).
  A point should be clarified here. There will be several places in the Quran where waging war against the
  mushrikeen is advocated. This does not mean that Muslims go to war against the world’s mushrikeen in
  any case. At these places the mushrikeen at the time of revelation of the Quran are meant, that had created
  conditions that led to battles. Thus war will be waged only against those who create that sort of
  conditions. In other words, there will be no war against mushrikeen only because they are mushrikkeen.
  War will be fought only with those who create war-like conditions. For this there are detailed orders in
  the Quran.
  But the position of the mushrikeen and the relationship with them which the Quran has determined will
  remain the same always.
  Whatever has come above means that:
  - To think that anyone shares the forces and authority reserved for Allah alone, is shirk.
  - To think that one is subservient or obedient to any force or human being except Allah, or is
  bowed before is shirk.
  - To accept the supremacy of anyone or anything except the Quran is shirk, and to follow any law
  excepting this law is shirk.
  - Deen formulates unity within the nation of believers of Allah. To be divided into sects is shirk.
  - One God, one code of life given by Him, its followers is one nation, one system for this nation.
  This is what oneness is. Anything besides it is shirk.LUQ
