Diet is the foundation of medicine and the stomach is the foundation of illness

Is this a Hadith?

‘Diet is the foundation of medicine and the stomach is the foundation of illness’

Answer:

This is more accurately recorded as the statement of Al Harith ibn Kaladah, the Arab doctor.

These words have also been recorded as a Hadith of Nabi (sallallahu ‘alayhi wa sallam), however, ‘Allamah ibn Rajab Al Hambali and ‘Allamah Sakhawi (rahimahumallah) have dismissed the authenticity.

(Jami’ul ‘Ulumi Wal Hikam, vol. 2 pg. 334, Hadith: 47 and Al Maqasidul Hasanah, Hadith: 1035)

And Allah Ta’ala Knows best.
