Blow are the pictures belong to the rivers from South Africa near to Cape Town. These two rvier's speciality was discovered begining on 20th century but, Almighty Allah has already mentioned it in the Holly Quran 1400 years back, for ref see (Surah Rehman). The speciality of these two rivers is that both are running in the same sea but, the taste of water is not same and, they never mix with each other (By the order of Almighty God), one river's water taste is sour and other one is sweet. (Subhan Allah)
