Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
"... Join not in worship others with Allah. Verily! Joining others in worship with Allah is a great Ẓulm (wrong) indeed." (V.31:13)
Narrated `Abdullah:
When there was revealed: 'It is those who believe and confuse not their beliefs with wrong.' (6.82) It was very hard for the companions of Allah's Messenger (ﷺ), so they said, "Which of us has not confused his belief with wrong?" Allah's Messenger (ﷺ) said, "The Verse does not mean this. Don't you hear Luqman's statement to his son: 'Verily! Joining others in worship, with Allah is a great wrong indeed.' (31.13)
