Five Essential Qualities of a Mufti

Ibn Battah records that Imām Ahmad – Allāh have mercy on him – said:

No man should appoint himself to issue verdicts (fatwa) until and unless he fulfills five characteristics: First, he should have a [firm and good] intention; for if he does not, he will have no light upon him, and nor will his words. Second, he should be forbearing, tranquil and serene. Third, he should be strong upon what he is involved in, strong in its knowledge. Fourth, he should have sufficient means (wealth), otherwise the people will chew him up. Fifth, he should know people and their ways.
