Do not disparage your friend's repentance!

Title: Do not disparage your friend's repentance! Description: Before you mock your friend for starting to leave a sin... Aren't you ashamed to be late in repenting, then become an obstacle in the path of someone who is returning? Remember that your friend might be fighting himself in the early stages, and your words could be a push forward or a pull backward, to the point where he may not think about repenting again. So consider which one you would like to be in the balance of your deeds!
