Types of Injustice Mentioned in the Qur'an and the Meaning of Shirk in Them

Question:
And if the Shaykh has erred, may Allah guide you, is every instance of injustice mentioned in the Qur'an interpreted to mean shirk (associating partners with Allah), or is this specific to the verse in which the Messenger (peace and blessings be upon him) interpreted injustice as shirk?

Answer:
Injustice is of three types. The first is injustice in the sense of shirk (associating partners with Allah), and this is the greatest of the types of injustice, . The second is the servant's injustice to himself through disobedience and sins. The third is the servant's injustice to people by taking their wealth, or beating them, or killing them, or otherwise transgressing against them. These are the types of injustice: the first is shirk, whereas the servant's injustice to himself and the servant's injustice to people is not shirk; rather, it is aggression and a sin among the sins that are less than shirk.
