Below Photos show two rivers flowing in southern part near Cape Town, South Africa. These rivers flow together naturally. ALLAH (SWT) has mentioned the nature of these two rivers in Holy Quran. Taste of one river is said to be sweet whereas the taste of the other is said to be the opposite (that is bitter) but they never mix. There is nothing in between these rivers which stops them from mixing together. One of ALLAH (SWT)’s CREATIONS !
அவனே, இரண்டு கடல்களையும் ஒன்றோடொன்று சந்திக்க செய்தான், ஆயினும் அவற்றிடையே ஒரு தடுப்பும் இருக்கிறது அதை அவை மீறமாட்டா. (அல்குா்ஆன் 55:19,20)
