Sahih al-Bukhari 2:25
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 Messenger (ﷺ) 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)

حَدَّثَنَا أَبُو الْوَلِيدِ، قَالَ حَدَّثَنَا شُعْبَةُ، ح. قَالَ وَحَدَّثَنِي بِشْرٌ، قَالَ حَدَّثَنَا مُحَمَّدٌ، عَنْ شُعْبَةَ، عَنْ سُلَيْمَانَ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ، قَالَ لَمَّا نَزَلَتِ {الَّذِينَ آمَنُوا وَلَمْ يَلْبِسُوا إِيمَانَهُمْ بِظُلْمٍ} قَالَ أَصْحَابُ رَسُولِ اللَّهِ صلى الله عليه وسلم أَيُّنَا لَمْ يَظْلِمْ فَأَنْزَلَ اللَّهُ {إِنَّ الشِّرْكَ لَظُلْمٌ عَظِيمٌ}.
