The one who provides for all of His servants, there is not a creature on the earth except that Allah provides for it. His providing for His servants is of two types: 1) The general provision which extends to the righteous and the sinner, the first and the last. This is the provision that is required by the bodies. 2) The specific provision - this being granted to the hearts, nourishing them with knowledge and faith. Also the lawful provision that has been appointed for the benefit of the religion, this being specific to the believers and apportioned in accordance to their differing levels and what His wisdom and mercy dictate.
“Say: Come I will recite to you what your Lord has prohibited you from: Join not anything in worship with Him; be good and dutiful to your parents; kill not your children because of poverty - We provide sustenance for you and for them; come not near shameful sins whether openly or secretly; kill not anyone who Allah has forbidden except for a just cause. This He has commanded you that you may understand.”
[al-An'am (6): 151]
“I created man and jinn only that they may worship Me. I seek not any provisions from them nor do I ask that they feed Me. Indeed Allah is ar-Razzaq, Owner of Strength, the Powerful.”
[adh-Dhariyat (51): 56-58]
