وَٱخْتَارَ مُوسَىٰ قَوْمَهُۥ سَبْعِينَ رَجُلًۭا لِّمِيقَٰتِنَا ۖ فَلَمَّآ أَخَذَتْهُمُ ٱلرَّجْفَةُ قَالَ رَبِّ لَوْ شِئْتَ أَهْلَكْتَهُم مِّن قَبْلُ وَإِيَّٰىَ ۖ أَتُهْلِكُنَا بِمَا فَعَلَ ٱلسُّفَهَآءُ مِنَّآ ۖ إِنْ هِىَ إِلَّا فِتْنَتُكَ تُضِلُّ بِهَا مَن تَشَآءُ وَتَهْدِى مَن تَشَآءُ ۖ أَنتَ وَلِيُّنَا فَٱغْفِرْ لَنَا وَٱرْحَمْنَا ۖ وَأَنتَ خَيْرُ ٱلْغَٰفِرِينَ
And Moses chose of his people seventy men for Our appointed tryst and, when the trembling came on them, he said: My Lord! If Thou hadst willed Thou hadst destroyed them long before, and me with them. Wilt thou destroy us for that which the ignorant among us did? It is but Thy trial (of us). Thou sendest whom Thou wilt astray and guidest whom Thou wilt: Thou art our Protecting Friend, therefore forgive us and have mercy on us, Thou, the Best of all who show forgiveness.
Surah Al-A'raaf(7:155)
