YUSUFALI: And remember Moses prayed for water for his people; We said: "Strike the rock with thy staff." Then gushed forth therefrom twelve springs. Each group knew its own place for water. So eat and drink of the sustenance provided by Allah, and do no evil nor mischief on the (face of the) earth.
Interesting story that mix up 2 bible stories:
1.The twelve springs - And they came to Elim, where were twelve springs of water, and three score and ten palm-trees; and they encamped there by the waters. (Exodus 15:27)
2.Water from the Rock - And all the congregation of the children of Israel journeyed from the wilderness of Sin, by their stages, according to the commandment of the LORD, and encamped in Rephidim; and there was no water for the people to drink...And the LORD said unto Moses: 'Pass on before the people, and take with thee of the elders of Israel; and thy rod, wherewith thou smotest the river, take in thy hand, and go. Behold, I will stand before thee there upon the rock in Horeb; and thou shalt smite the rock, and there shall come water out of it, that the people may drink.' And Moses did so in the sight of the elders of Israel. (Exodus 17:1-6)
So there where 2 different stories that took place in 2 different places(Elim-Rephidim) that mixed into one story in Quran.
Muslims usually claim that the Bible was changed and not authentic,one should ask himself what is more likely to happen, 2 stories that mix into one or the other way round?
