وَقَطَّعْنَاهُمُ اثْنَتَيْ عَشْرَةَ أَسْبَاطًا أُمَمًا ۚ وَأَوْحَيْنَا إِلَىٰ مُوسَىٰ إِذِ اسْتَسْقَاهُ قَوْمُهُ أَنِ اضْرِب بِّعَصَاكَ الْحَجَرَ ۖ فَانبَجَسَتْ مِنْهُ اثْنَتَا عَشْرَةَ عَيْنًا ۖ قَدْ عَلِمَ كُلُّ أُنَاسٍ مَّشْرَبَهُمْ ۚ وَظَلَّلْنَا عَلَيْهِمُ الْغَمَامَ وَأَنزَلْنَا عَلَيْهِمُ الْمَنَّ وَالسَّلْوَىٰ ۖ كُلُوا مِن طَيِّبَاتِ مَا رَزَقْنَاكُمْ ۚ وَمَا ظَلَمُونَا وَلَٰكِن كَانُوا أَنفُسَهُمْ يَظْلِمُونَ

We divided them into twelve tribes or nations. We directed Moses by inspiration, when his (thirsty) people asked him for water: "Strike the rock with thy staff": out of it there gushed forth twelve springs: Each group knew its own place for water. We gave them the shade of clouds, and sent down to them manna and quails, (saying): "Eat of the good things We have provided for you": (but they rebelled); to Us they did no harm, but they harmed their own souls.
