Al-Mughni (المغني): Meaning of Allah’s Name

He is Self-Sufficient, completely and unrestrictedly, deference is given to His perfection and the perfection of His Attributes. He has absolutely no deficiency of any kind; it is not possible that He be anything but Self-Sufficient, for self-sufficiency is from the necessary consequences of His Essence. Similarly it is not possible for Him to be anything but the Creator, the All-Powerful, the Provider and the Bestower of good. He is not in need of anything or anyone, He is the Self-Sufficient in Whose Hand lie the treasures of the heavens and the earth, and the treasures of this life and the Hereafter. He suffices for the whole of His creation generally, and is specifically sufficient for the believers in that He confers upon their hearts nurturing knowledge and the realities of faith.

"Kind words and forgiving faults are better than giving in charity. Allaah is the Rich, the Forebearing." (2:263)

"And your Lord is Self-Sufficient, full of Mercy. If He Will He could destroy you and out in your place make who He Will to be successors, just as He raised you from the seed of another people." (6:133)
