وَجَعَلْنَا فِيهَا رَوَاسِيَ شَامِخَاتٍ وَأَسْقَيْنَاكُم مَّاء فُرَاتًا
[77:27]
And made therein lofty mountains, and given you to drink of sweet water?
And made therein mountains standing firm, lofty (in stature); and provided for you water sweet (and wholesome)?
And placed therein high mountains and given you to drink sweet water therein?
