Hadhrat Mawlana Wasiullah (may Allah have mercy on him) said,

“The worst lethal thing (for a seeker) is the companionship (suhba) of an individual who is deficient (spiritually).

I define this deficient person as someone who has no grief on lacking perfection (kamal) and is not remorseful for his debilitated state (hal) of affairs.

The person who is aware of his imperfections (and is working on removing them), although not qualified completely as yet, is however, headed towards the right direction. His companionship is not harmful.”
