Iyaz bin Himar (may Allah be pleased with him) relates that the Holy Messenger (may Allah bless and greet him) said: “Allah, the Most Exalted, has revealed to me that you should show courtesy and be cordial with each other so that nobody should consider himself superior to another nor harm him.”
Cordiality or politeness is one of the salient traits of a civilized human being. It costs nothing but earns much credit. It is in fact this single trait of human character that distinguishes a civilized man from an uncivilized one in society. Since Islam aims at making a person man in the real sense of the term, it moulds the very inner traits of those who vows and strives to live by its teachings.
Here the Holy Messenger (may Allah bless and greet him) reveals the Divine wish that one should be kind, courteous, cordial and humble towards others. A Muslim in particular should be kind, gentle and considerate. He should never use his strength against others. His abilities, influence, power, physical strength and economic prowess should not be used for the purpose of either suppressing, persecuting or causing harm to others. And for this one ought to be gentle, merciful, sympathetic and mild-tempered. By virtue of the intensity of his faith, sincerity of his character, and his insight and perspicacity, a Muslim should work for the welfare and well-being of the Ummah.
On many occasions, the Holy Messenger (may Allah bless and greet him) enjoined his followers to be polite with one another. In a very oft-quoted hadith he says, “A Muslim is he from whose tongue and hands other Muslims are safe.”
In the eyes of Islam nobody is superior to others save and except in terms of piety. This is the fruit of being cordial and courteous. If one is kind and considerate towards his fellow beings, he will not consider himself superior to others. And to be kind and cordial, it is necessary that one shuns the idea of being superior to others however power and prowess he wields.
