When it is too late to repent

Surah 7 Verse 5

When Allah's punishment comes, it is too late to repent then. They were given the chance to repent but chose not to. Another relevant example is the case of Pharoah who cried out that he believed as the sea closed in on him.

We have many chances to change our ways, but waiting until the last moment is never a good idea. Remember that Imaan is belief in the unseen! It is not Imaan to say I believe when one can see the angels, etc.
