I have read that drinking the leftover water from wudu is a Sunnah and is the cure from seventy diseases .
Please advise on the authenticity of this.
Drinking the left over water after wudu is a Sunnah, as has been recorded in Sunan Nasai and other Hadith sources. (Sunan Nasai; Al Mujtaba Hadith: 95)
However, the narration in question is unreliable. It is recorded in At Targhib Fi Fadailil A’amal of Imam Ibn Shahin (rahimahullah).
(At Targhib Fi Fadailil A’amal, Hadith: 536)
The Muhaddithun have declared the narration a fabrication due to a liar in the chain.
(Dhaylul La-Alil Masnu’ah, vol. 2 pg. 561, Hadith: 679, Tanzihush Shari’ah, vol. 2 pg. 265)
And Allah Ta’ala Knows best.
