[So] how pitiful is the one who is prevented from goodness in his old age for sins committed during [his] youth!
It is not befitting for the believer to begin the day or the evening except in a state of repentance, for indeed he does not know when death may strike – [whether] in the morning or the evening.
If someone made the intention to commit a sin, but did not do it, would it be recorded against him or not?
So whoever commits [a deed] which Allaah and His Messenger have forbidden, has harmed his religion; and he must remedy this harm by repentance and turning back [to Allaah].
[Sometime ago] I stole about five car covers, and after I had repented [from doing so], I felt remorse about what I had done. I felt this remorse was of no benefit to me, so I began to wish for my hands to be cut-off! [So] before I do this, guide me [to that which is correct regarding my situation], and may Allaah reward you?
