Kindness and Gentleness

Two: To have Hikmah when differing means we should rarely depart from an atmosphere of kindness and gentleness, we should seldom allow ourselves to become angry and raise our voices.

Fir'own (Pharaoh) was one of the evilest people that lived. Musa was one of the noblest. Look at how Allah told Musa to advise Fir'own...

"Go, both of you, to Fir'own. Indeed, he has transgressed. And speak to him with gentle speech, perhaps he may remember or fear (Allah)."
A man once entered upon the Khalifah and chastised him for some policies he had taken. The Khalifah replied, "By Allah, Fir'own was more eviler than me. And by Allah, Musa was more pious than you. Yet, Allah commanded him...'And speak to him with gentle speech, perhaps he may remember or fear (Allah).'"
