Which scripture says that during eclipse all water become pure like Ganges water?
Parashar Smriti, Chapter 12 source 1 source 2 says , during eclipse all waters become pure like Ganges.
सर्वं गंगा समं तोयं राहुग्रस्ते दिवाकरे।
सोमग्रहे तथैवोक्तं स्नानदानादि कर्मसु।।
When the sun or the moon is seized by rahu, all water becomes as pure as the water of the Ganga, so far as bathing and giving, and other religious rites are concerned.
