Is this a Hadith?
‘Diet is the foundation of medicine and the stomach is the foundation of illness’
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.
