The Spider - 29:6 Whoever strives for Us strives for himself. Allah is not in need of anyone.
Allah is not in need of you unless you strive, and He is rich and powerful to replace you with a people who will strive:
The Table Spread/5:54 Believers, whoever turns away from his religion, know this: Allah brings a people whom He loves, and they love Him. They are humble towards the believers and strong and firm against the disbelievers. They strive hard in the way of Allah and do not fear the condemnation of those who condemn. This is the bounty of Allah; He gives it to whom He wills. Allah is Generous, Knowing.

The Women/4:131 "To Allah belongs whatever is in the heavens and whatever is in the earth. We admonished those to whom the Book was given before you and to you as well, saying, "Remember Allah."If you disbelieve, know that whatever is in the heavens and whatever is in the earth belongs to Allah. Verily, Allah is not in need of anyone and is worthy of praise."
The Women/4:132 To Allah belongs whatever is in the heavens and whatever is in the earth. Allah is sufficient as a protector.

Originator/35:16 If He wills, He will take you away and bring in your place new creatures.

Muhammad/47:38 You are called to spend in the Way of Allah, but some of you are stingy. Whoever is stingy is stingy towards himself. Allah is rich and you are poor. If you turn away, He will replace you with another people, but they will not be like you.
