Answered by Sayyidi Habib Umar bin Hafiz (may Allah protect him and benefit us by him)
If someone is able to start a business should they do so? Is there a contradiction between going into business and relying upon Allah (tawakkul)?
The one who is able to do business and has lawful means should do so with a good intention but this should not distract him from doing something which is more important. In his business, he should intend to benefit others. A believer must rely upon Allah whether he is in business or not. This entails that he repels any fear of poverty or concern about his provision. Most people take the means to earn their provision whereas others do not. Regardless of the state that has been facilitated for them they should rely upon Allah and proceed with a tranquil heart.
