On the authority of Al-Mamūn رحمه الله he said:
“The people are of three categories:
- A person from amongst them who is similar to nourishment which is a must to have ( in one’s life).
- From them is the one who is like medication that one is need of in time of sickness.
- From amongst them is the one who is like the disease, detested in all situations.”
[Siyar A’lām An-Nubalā 10/281-282 of Imām Adh-Dhahabī رحمه الله]
