In the name of Allah, the Beneficent, the Merciful

Three things are indispensable for a believer in all conditions of life:

1. He should keep the commandments of God.

2. He should abstain from the forbidden things.

3. He should be pleased with the decree of Providence.

Thus the least that is expected of a believer is that he should not be without these three things. So he should make up his mind for these and talk to himself about them and keep his organs engaged in them.
