The Thunder - 13:11
(For each of them) there are those who watch him from in front of him and from behind him. They guard him by Allah´s command. Unless a community changes itself, Allah does not change their condition. And when Allah wills evil for a people, no power can stop it, nor do they have any protector except Him.
When does Allah wish evil for a people?
The Night Journey/17:16
When We wish to destroy a community, We allow its prominent wealthy people to do evil there. Thus the promise to that community is fulfilled and We destroy it.
The Cattle/6:123
We have given permission to the leading criminals of every country to deceive and plot therein. Indeed they deceive none but themselves. But they do not realize it.
The Sandhills/46:35
Be patient, as the apostles who had resolution and determination were patient, and do not hasten for them. When they see what is promised to them, it is as if they had remained in the world for an hour of the day. This is a declaration: Who will be destroyed but a people who have gone astray?
The Cattle/6:47
"Say: "If the torment of Allah comes upon you suddenly or after an announcement. Who will be destroyed but an unjust people?"
The Stories/28:59
Your Lord does not destroy a people until He sends to their center a messenger who recites to them Our Verses. And We never destroy a people whose people are not oppressors.
