Why is shirk injustice?

Injustice means places something at its WRONG place, i.e, where it does not belong. In shirk a person Wrongly attributes the powers which belong to Almighty Allah. Try to undestand. Belief in Almighty Allah (God) Sura Baqra -2. Aya 163: "And your Allah is ONE Allah, There is no god but He…." He is the Sole Creator, Sustainer, Provider, Helper and Ruler of the Universe. He has No Son, No Parents, No Off-spring. He is Omnipotent, Omni-Present, All-Knowing, All-Seeing, All-Listening. HE and He alone deserves worship. All powers lie in His Mighty Hands. He alone is the Master of the Day of Judgment. He has No Partner, No Associate, whatsoever. No one can understand Him completely. All honor, respect, admiration is due to Him. NO ONE can help anybody, not even his own self, if He does not wish. NO ONE can do any harm to anybody if he does not wish so. Even all the holy Prophets (May blessings of Allah Almighty be on them all) joined together can't create a blade of grass against His Will. There is Nothing like Him. He is Most Merciful, Most Gracious, Most Forgiving.

Now we come to Shirk and its kinds. Following are two kinds of shirk:

1. Shirk in the personality of Almighty Allah. Having this belief that there are other gods as well who deserve same respect and should be worshipped as Almighty Allah.

2. Shirk in the Attributes of Almighty Allah. Having this belief that Allah Almighty has delegated some of His powers to Prophets or holy people. They can also exercise these powers independently as and when they like. Now you can think for yourself how shirk is contrary to the Belief in Oneness (Tauheed) of Almighty Allah.

Thus Shirk is the Unpardonable sin. It is the greatest Injustice to worship any other than Almighty Allah as He alone deserves it.
