Hazrat Mufti Ebrahim Salejee (Daamat Barakaatuhu) mentioned:
The most precious commodity is imaan. The nature of anything precious is that if it is looked after then its benefits are tremendous, and on the contrary if it is neglected then the consequences are disastrous. If this imaan is strengthened, it can cause a person to transcend even above the angels. But if it is neglected, it can demote a person to the lowest of positions. Hence, there is a need to guard and secure this invaluable asset of imaan. For this, the Quraan Kareem enjoins two things, viz. adopting taqwa and associating with the pious.
