Iyaz bin Himar relates that the Holy Prophet Muhammad ﷺ 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.”
(Muslim)
Cordiality is a great virtue. It helps run the cycle of social life smoothly. It is in fact the single salient trait of human character which distinguishes a civilized man from an uncivilized one in society. Since Islam aims at making a man man in the real sense of the term, it moulds the very inner traits of those who pledge to live by its teachings and thereby earn the pleasure of Allah the Exalted.
Here the Holy Prophet ﷺ reveals the Divine wish that one should be humble towards another. A Muslim should be kind, gentle and considerate. He should never use his strength and power against others. His ability, influence, wealth, shrewdness and physical prowess should not be used for the purpose of either suppressing, persecuting or causing harm to others. One ought to be gentle, merciful, sympathetic and mild-tempered. By virtue of the intensity and firmness of his faith, the sincerity of character and insight and perspicacity, a Muslim should work for the welfare and well-being of the society he lives in.
On many occasions, the Holy Prophet ﷺ asked his followers to be polite with one another. Once the society follows these Prophetic guidelines, it can taste the sweetness they promise.
