Praise be to Allah, the Lord of the Worlds, and peace and blessings upon our Master Muhammad, the Faithful and the Honest.

Allah's Name Ar-Razzaq (All-Provider): 

Dear Noble brothers, we will start discussing a Beautiful Name of Allah the Almighty, and it is Allah's Name Ar-Razzaq. 

The main point I would like to highlight is that Rizaq (provision) is not limited to mean money, food, and drink, and the proof is Allah's following Words: 

(And instead (of thanking Allah) for the provision He gives you, on the contrary, you deny Him (by disbelief)!)

[Al-Waqi'ah, 82]

When man gets himself acquainted with Allah, this is provision from Allah the Almighty. Besides, if Allah the Almighty makes man feel secure, then this security is a provision from Allah. Also, if Allah the Almighty casts satisfaction into man's heart, this is considered provision, if Allah casts tranquility into his heart, it is considered provision, and if Allah the Almighty casts mercy into his heart, this is considered provision. Hence, the meaning of provision is wider than a reference to money, food and drink. In fact, provision is the blessing bestowed upon you, and you are pleased about it.      

Due to the Favor of Allah, Exalted and Sublime be He, upon you, He has created provision to you and made it in harmony with your creation. In addition, He has created the means of provision as well. For instance, everyone has a craft, a profession or a job due to the skills and experiences he has. You can notice how someone works in trade, another one works in industry, someone else works in agriculture, another one works in medicine, other one works in engineering, someone else works in teaching, another one works in physics, someone else works in chemistry and another man works in law (to solve people's problems) and so on
you can put all these in one sentence without repeating the someone. 
Others  work in agriculture, medicine, engineering, teaching, physics, chemistry and law and so on .  

Hence, each man makes a living from a craft or from accumulated experiences he has, so that he can earn money. 

Allah, Exalted and Sublime be He, provides you with means of provision, as the following Ayah indicates precisely:       

(And surely, We gave you authority on the earth and appointed for you therein provisions (for your life). Little thanks do you give.)

[Al-A'araf, 10]

This means Allah the Almighty grants you effective means to make a living and have provision.  However, dear brothers, making a living basically depends on making use of all available means of provision and then trusting in Allah the Almighty.  

Praise be to Allah, the Lord of the Worlds, and peace and blessings upon our Master Muhammad, the Faithful and the Honest.
