1. 7:145 وَكَتَبْنَا لَهُۥ فِى ٱلْأَلْوَاحِ مِن كُلِّ شَىْءٍ مَّوْعِظَةً وَتَفْصِيلًا لِّكُلِّ شَىْءٍ فَخُذْهَا بِقُوَّةٍ وَأْمُرْ قَوْمَكَ يَأْخُذُوا۟ بِأَحْسَنِهَا سَأُو۟رِيكُمْ دَارَ ٱلْفَٰسِقِينَ

   And We ordained for him in the tablets admonition of every kind and clear explanation of all things; so take hold of them with firmness and enjoin your people to take hold of what is best thereof; I will show you the abode of the transgressors.
   

2. 7:150 وَلَمَّا رَجَعَ مُوسَىٰٓ إِلَىٰ قَوْمِهِۦ غَضْبَٰنَ أَسِفًا قَالَ بِئْسَمَا خَلَفْتُمُونِى مِنۢ بَعْدِىٓ أَعَجِلْتُمْ أَمْرَ رَبِّكُمْ وَأَلْقَى ٱلْأَلْوَاحَ وَأَخَذَ بِرَأْسِ أَخِيهِ يَجُرُّهُۥٓ إِلَيْهِ قَالَ ٱبْنَ أُمَّ إِنَّ ٱلْقَوْمَ ٱسْتَضْعَفُونِى وَكَادُوا۟ يَقْتُلُونَنِى فَلَا تُشْمِتْ بِىَ ٱلْأَعْدَآءَ وَلَا تَجْعَلْنِى مَعَ ٱلْقَوْمِ ٱلظَّٰلِمِينَ

   And when Musa returned to his people, wrathful (and) in violent grief, he said: Evil is it that you have done after me; did you turn away from the bidding of your Lord? And he threw down the tablets and seized his brother by the head, dragging him towards him. He said: Son of my mother! surely the people reckoned me weak and had well-nigh slain me, therefore make not the enemies to rejoice over me and count me not among the unjust people.
