Do not be afraid of poverty when following Allah's command

Surah 9 Verse 28
Allah is telling the muslims not to be afraid of loss of business because of the fact that non-Muslims will not be able to come from next year.
If you follow Allah's command he will enrich you.

There is an interesting analogy with this verse to present day situation.
Tourism
Many Muslim countries nowadays 'bend over backwards' to please non-Muslim tourists in the thirst for foreign currency. This is very similar to the situation of the Muslims when they were worried about losing business when non-Muslims were prohibited from Makkah.
Don't lose your faith for worldly gain. Do not allow non-Muslim practices in your country. In the end you will lose your own practice.

Instead of going for tourism, go for education, innovation, technology.
Allah will open a way if you put your mind to it.
