Al-Ghani
Allah is Al-Ghaniyy, He is The One who is self-sufficient and independent. He does not need anything as He is completely satisfied and free from dependence. Allah is The One whose wealth and riches all others depend on.
From the root gh-n-y which has the following classical Arabic connotations: to be free from wants or needs to be self-sufficient, independent to be able to do without help from others to be content, satisfied to be rich, wealthy, flourishing.
Here you are – those invited to spend in the cause of Allah – but among you are those who withhold [out of greed]. And whoever withholds only withholds [benefit] from himself;
and Allah is the Free of need, while you are the needy. And if you turn away, He will replace you with another people;
then they will not be the likes of you. (Quran 47:38)
If you disbelieve – indeed, Allah is Free from need of you. And He does not approve for His servants disbelief. And if you are grateful, He approves it for you;
and no bearer of burdens will bear the burden of another. Then to your Lord is your return, and He will inform you about what you used to do. Indeed, He is Knowing of that within the breasts. (Quran 39:7)
[Those] who are stingy and enjoin upon people stinginess. And whoever turns away – then indeed, Allah is the Free of need, the Praiseworthy. (Quran 57:24)
