﴿ ۞ قَالَ أَلَمْ أَقُل لَّكَ إِنَّكَ لَن تَسْتَطِيعَ مَعِىَ صَبْرًۭا ﴾

“He replied: "Did I not tell thee that thou wilt never be able to have patience with me?"”

He said ‘Did I not say to you that you would never be able to bear with me?’ laka ‘to you’ has been added to that same statement which was made before because this time there could not be any excuse for Moses’s impatience.
