When the Verse:-- 'Those who believe and mix not their belief with wrong." was revealed, the companions of the Prophet ﷺ said, "Who amongst us has not mixed his belief with wrong?" Then Allah revealed: "Join none in worship with Allah, Verily joining others in worship with Allah is a great wrong indeed."
لَمَّا نَزَلَتِ {الَّذِينَ آمَنُوا وَلَمْ يَلْبِسُوا إِيمَانَهُمْ بِظُلْمٍ} قَالَ أَصْحَابُ النَّبِيِّ ﷺ أَيُّنَا لَمْ يَلْبِسْ إِيمَانَهُ بِظُلْمٍ فَنَزَلَتْ {لاَ تُشْرِكْ بِاللَّهِ إِنَّ الشِّرْكَ لَظُلْمٌ عَظِيمٌ }
