في داخلي شُرْفَةٌلا يَمُرُّ بها أَحَدٌ للتَّحيَّة.

This quote is referring to the idea of learning from our mistakes. It means that if we make a mistake, we should take the time to reflect on it, understand why it happened, and then use what we learn from the mistake to make sure it doesn’t happen again. In other words, we should use this opportunity to learn something new that can help us in the future. By doing this, we can grow and become better versions of ourselves.
