﴿ وَإِذْ قَالَ مُوسَىٰ لِقَوْمِهِۦٓ إِنَّ ٱللَّهَ يَأْمُرُكُمْ أَن تَذْبَحُوا۟ بَقَرَةًۭ ۖ قَالُوٓا۟ أَتَتَّخِذُنَا هُزُوًۭا ۖ قَالَ أَعُوذُ بِٱللَّهِ أَنْ أَكُونَ مِنَ ٱلْجَٰهِلِينَ ﴾

“AND LO! Moses said unto his people: "Behold, God bids you to sacrifice a cow." They said: "Dost thou mock at us?" He answered: "I seek refuge with God against being so ignorant!"”

And mention when Moses said to his people when one among them was killed and the killer was not known and so they asked Moses to pray to God to reveal the killer which he did; ‘God commands you to sacrifice a cow’. They said ‘Do you take us in mockery?’ that is making fun of us when you answer us like this? He said ‘I take refuge with I seek defence with God lest I should be one of the ignorant’ one of those who indulge in mockery.
