"It is those who believe (in the Oneness of Allah and worship none but Him Alone) and confuse not their belief with Zuim (wrong i.e., by worshipping others besides Allah).. ." (V.6:82)

Sahih al-Bukhari 4629

Narrated `Abdullah:

When:"...and confuse not their belief with wrong." (6.82) was revealed, the Prophet's companions said, "Which of us has not done wrong?" Then there was revealed:-- "Verily joining others in worship with Allah is a tremendous wrong indeed." (31.13)

حَدَّثَنِي مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ، عَنْ شُعْبَةَ، عَنْ سُلَيْمَانَ، عَنْ إِبْرَاهِيمَ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ لَمَّا نَزَلَتْ ‏{‏وَلَمْ يَلْبِسُوا إِيمَانَهُمْ بِظُلْمٍ‏}‏ قَالَ أَصْحَابُهُ وَأَيُّنَا لَمْ يَظْلِمْ فَنَزَلَتْ ‏{‏إِنَّ الشِّرْكَ لَظُلْمٌ عَظِيمٌ‏}
