سورة البقرة · 2:60

60. Remember, from Allah’s blessings upon you, when you were in the wilderness, and you suffered great thirst, so Moses prayed to his Lord and asked that He give you water. Allah commanded that he hit the rock with his stick, and when he hit it, twelve springs appeared from it, the same number as the number of your tribes. Water gushed from them, and Allah made clear to each tribe which was their spring to drink from, so that there would be no conflict between you. And He told you to eat and drink from what He provided for you, without any effort or work from you, and told you not to put your efforts into ruining things on earth.
