وَقَطَّعْنَٰهُمُ ٱثْنَتَىْ عَشْرَةَ أَسْبَاطًا أُمَمًۭا ۚ وَأَوْحَيْنَآ إِلَىٰ مُوسَىٰٓ إِذِ ٱسْتَسْقَىٰهُ قَوْمُهُۥٓ أَنِ ٱضْرِب بِّعَصَاكَ ٱلْحَجَرَ ۖ فَٱنۢبَجَسَتْ مِنْهُ ٱثْنَتَا عَشْرَةَ عَيْنًۭا ۖ قَدْ عَلِمَ كُلُّ أُنَاسٍۢ مَّشْرَبَهُمْ ۚ وَظَلَّلْنَا عَلَيْهِمُ ٱلْغَمَٰمَ وَأَنزَلْنَا عَلَيْهِمُ ٱلْمَنَّ وَٱلسَّلْوَىٰ ۖ كُلُوا۟ مِن طَيِّبَٰتِ مَا رَزَقْنَٰكُمْ ۚ وَمَا ظَلَمُونَا وَلَٰكِن كَانُوٓا۟ أَنفُسَهُمْ يَظْلِمُونَ
We divided them into twelve tribes, nations; and We inspired Moses, when his people asked him for water, saying: Smite with thy staff the rock! And there gushed forth therefrom twelve springs, so that each tribe knew their drinking-place. And we caused the white cloud to overshadow them and sent down for them the manna and the quails (saying): Eat of the good things wherewith we have provided you. They wronged Us not, but they were wont to wrong themselves.
Surah Al-A'raaf(7:160)
