There is no harm in the Prophet doing that which Allah has ordained for him; such has been the course of Allah with respect to those who have gone before; and the command of Allah is a decree that is made absolute:

(Such has been) the course of Allah with respect to those who have gone before; and you shall not find any change in the course of Allah.

But their belief was not going to profit them when they had seen Our punishment; (this is) Allah's law, which has indeed obtained in the matter of His servants, and there the unbelievers are lost.

Such has been the course of Allah that has indeed run before, and you shall not find a change in Allah's course.
