Hazrat Mufti Ebrahim Salejee (Daamat Barakaatuhu) mentioned:
There are two types of injunctions. One is that which relates to the outer-self (e.g. salaah, fasting, etc.), and the other is that which relates to the inner-self (e.g. ridding the heart from jealousy, pride, etc.). Rectifying the inner-self is also imperative and it cannot be achieved without a tutor (shaikh).
