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." (Using translation from Bukhārī 3428)
لَمَّا نَزَلَتْ {الَّذِينَ آمَنُوا وَلَمْ يَلْبِسُوا إِيمَانَهُمْ بِظُلْمٍ} [الأنعام 82] قَالَ أَصْحَابُ رَسُولِ اللهِ ﷺ أَيُّنَا لَمْ يَلْبِسْ إِيمَانَهُ بِظُلْمٍ؟ قَالَ فَنَزَلَتْ {لَا تُشْرِكْ بِاللهِ إِنَّ الشِّرْكَ} [لقمان 13] لَظُلْمٌ عَظِيمٌ
