ثُمَّ تَوَلَّيْتُم مِّنۢ بَعْدِ ذَٰلِكَ ۖ فَلَوْلَا فَضْلُ ٱللَّهِ عَلَيْكُمْ وَرَحْمَتُهُۥ لَكُنتُم مِّنَ ٱلْخَـٰسِرِينَ
Then you turned away after that. And if not for the favor of Allah upon you and His mercy, you would have been among the losers.
وَلَقَدْ عَلِمْتُمُ ٱلَّذِينَ ٱعْتَدَوْا۟ مِنكُمْ فِى ٱلسَّبْتِ فَقُلْنَا لَهُمْ كُونُوا۟ قِرَدَةً خَـٰسِـِٔينَ
And you had already known about those who transgressed among you concerning the sabbath, and We said to them, "Be apes, despised."
وَإِذْ قَالَ مُوسَىٰ لِقَوْمِهِۦٓ إِنَّ ٱللَّهَ يَأْمُرُكُمْ أَن تَذْبَحُوا۟ بَقَرَةً ۖ قَالُوٓا۟ أَتَتَّخِذُنَا هُزُوًا ۖ قَالَ أَعُوذُ بِٱللَّهِ أَنْ أَكُونَ مِنَ ٱلْجَـٰهِلِينَ
And [recall] when Moses said to his people, "Indeed, Allah commands you to slaughter a cow." They said, "Do you take us in ridicule?" He said, "I seek refuge in Allah from being among the ignorant."
قَالُوا۟ ٱدْعُ لَنَا رَبَّكَ يُبَيِّن لَّنَا مَا هِىَ ۚ قَالَ إِنَّهُۥ يَقُولُ إِنَّهَا بَقَرَةٌ لَّا فَارِضٌ وَلَا بِكْرٌ عَوَانٌۢ بَيْنَ ذَٰلِكَ ۖ فَٱفْعَلُوا۟ مَا تُؤْمَرُونَ
They said, "Call upon your Lord to make clear to us what it is." [Moses] said, "[Allah] says, 'It is a cow which is neither old nor virgin, but median between that,' so do what you are commanded."
