Q 15:5

And never did We destroy a township but there was a known decree for it (4)No nation can advance its term, nor delay it (5) Every Township has its allotted Time Allah is informing us that He never destroys a township until He has established evidences for it and its allotted time has ended. When the time for a nation's destruction has come, He never delays it, and He never moves its appointed time forward. This was a message and a warning to the people of Makkah, telling them to give up their Shirk, their stubbornness and disbelief for which they deserved to be destroyed.
