(23) CHAPTER. Zulm (wrong) of one kind can be greater or lesser than that of another.
Narrated 'Abdullah: When the following Verse was revealed: It is those who believe and confuse not their belief with wrong (worshipping others besides Allah.) (6:83), the companions of Allah's Apostle asked, Who is amongst us who had not done injustice (wrong)? Allah revealed: No doubt, joining others in worship with Allah is a great injustice (wrong) indeed. (31.13)
