۞ وَإِذِ اسْتَسْقَىٰ مُوسَىٰ لِقَوْمِهِ فَقُلْنَا اضْرِب بِّعَصَاكَ الْحَجَرَ ۖ فَانفَجَرَتْ مِنْهُ اثْنَتَا عَشْرَةَ عَيْنًا ۖ قَدْ عَلِمَ كُلُّ أُنَاسٍ مَّشْرَبَهُمْ ۖ كُلُوا وَاشْرَبُوا مِن رِّزْقِ اللَّهِ وَلَا تَعْثَوْا فِي الْأَرْضِ مُفْسِدِينَ (60)
(2:60) Remember that when Moses prayed for water for his people, We answered, "Strike the rock with your staff" : whereupon twelve springs gushed forth from it; *76 the people of every clan came to know their drinking place. (Then they were enjoined:) "Eat and drink of what Allah has provided and do not spread disorder on the earth."
*76) That rock can still be seen in the Sinai Peninsula with the twelve holes of the springs. Twelve springs were caused to flow for the Israelites in order to avoid water disputes among their twelve clans.
