And even less, if someone it may hurt.”
E quel che non si sa non si de' dire,
E tanto men, quando altri n'ha a patire.

Context: The sin of pride may be a small or a great thing in someone's life, and hurt vanity a passing pinprick or a self-destroying or even murderous obsession. Possibly, more people kill themselves and others out of hurt vanity than out of envy, jealousy, malice or desire for revenge.

“I hurt easy, I just don't show it, you can hurt someone and not even know it”

Patience, Sabr... And we think that the non-Muslims are our enemies – the minute we think that, automatically we will not be able to call them towards Islam. And they will get the wrong image of Islam. My brothers and sisters, Islam, it means peace, it stands for peace, it promotes peace, it teaches peace, and everything that you will achieve is peace. In this world peace, in the next peace, in your grave peace, with your children peace, in your environment peace. That is Islam. Anything that destroys that in any way is not Islam. Remember this.
