The Repentance - 9:39
If you do not act, He will punish you with a painful torment and replace you with another people. You can never harm Him. Allah is the Almighty.
Why does he wish to destroy us and bring a new people?
Prophet Jonah/10:13
How many generations before you We destroyed when they did wrong. Their messengers had gone to them with clear proofs, but they refused to believe. Thus do We punish the guilty people.
Prophet Jonah/10:14
Then We made you inheritors of the earth in their place, to see what you would do.
