He is Rich in His Essence. He is completely and absolutely rich. No defect occurs to His Supreme Attributes in any way and He cannot be but Al-Ghani (the Self-Sufficient), since this Attribute is a part of His Essence, just as He is the Creator, the All-Powerful, the Sustainer and the One Who Acts in a Good Manner. He does not need anyone in any way, since He is Al-Ghani (the Self-Sufficient), in Whose Hands there are the treasures of the Heavens and the earth, and the treasures of this world and the Hereafter, and He enriches all of His creation..
He is in no need of His slaves. He asks for no food or drink from them. He did not create them to have company after feeling lonely, or to have strength after feeling weak. On the contrary, they are in need of Him for their food and drink and all their matters. Allah says: 56- I did not create the jinn and mankind except to worship Me. 57- I do not want from them any provision, nor do I want them to feed Me (Az-Zâriyât: 56-57).
He bestows sustenance to His slaves to enrich them from poverty and need. He is never short of blessings and His slaves are in no need of anyone but Him. The following Hadeeth Qudsi says: &"O My servants, if the first of you and the last of you, and the humans of you and the jinn of you, were all to stand together in one place and ask of Me, and I were to give everyone what he requested, then that would not decrease what I possess except what is decreased of the ocean when a needle is dipped into it&" (Narrated by Muslim).
He enriches some of His slaves with guidance and righteousness of the heart by knowing Him, the Exalted, and glorifying and loving Him, thus enriching them with more than just worldly wealth.
O Allah, Your blessings and grants are without end, so enrich us with the good and permissible sustenance, for you are Al-Ghani, Al-Mughni.
