Allah has given us three warnings in this life. The worse of them is despair because that is coming from Shaytan. That is someone who has given up and doesn’t care any more. 

The second warning is that no one is going to help you. The third warning is don’t procrastinate. 

Shaytan always wants us to fall back. He tells us before we commit a sin “don’t worry about it, Allah will forgive you.” He tells us after we commit a sin “how could you do that?”
