al-Hasan al-Basri. Rizq (sustenance) is perhaps the most important driver of our worldly lives. The whole endeavor of seeking knowledge and acquiring skills has become a necessary tool towards Rizq is the provision made available to us to use, consume, or dispose of, such as food, transportation, and money. It is different from ownership, which constitutes proprietorship acquired through the means permitted by Islam. The Rizq of a person includes both the halal and haraam provisions at his/her disposal. hd9VE2.
