Someone had written to Hakim al-Umma Mawlana Ashraf ‘Ali Thanawi (Allah have mercy on him),
You have given ijaazat to a particular person but we do not see him to be fit for this position. Must we rely on your ijaazat or on what we see of him?

Hakim al-Umma replied,
‘You should act according to what you have witnessed and you are not bound by my ijaazat. There are various reasons for me giving ijaazat.’
