Al-A'raf 7:160 وقطعناهم اثنتي عشرة اسباطا امما واوحينا الى موسى اذ استسقاه قومه ان اضرب بعصاك الحجر فانبجست منه اثنتا عشرة عينا قد علم كل اناس مشربهم وظللنا عليهم الغمام وانزلنا عليهم المن والسلوى كلوا من طيبات ما رزقناكم وما ظلمونا ولاكن كانوا انفسهم يظلمون ١٦٠

We divided them into twelve tribes [as distinct] communities, and, when his people asked him for water, inspired Moses to strike the rock with his staff [so that] twelve springs gushed out. Each tribe knew its own drinking place; We gave them the shade of clouds and sent down to them manna and quails [saying], ‘Eat the good things We have provided for you.’ They did not wrong Us; it was themselves they wronged.
