Our beloved prophet Muhammad s.a.w.w never talked rude to any one, be it His enemy, even. Being followers of that great personality, we should also behave the same i.e kind and nice.
ALLAH swt said in Quran about those who were disbelievers and rude;
“In fact, whenever I call them (to say) that You might forgive them, they stick their fingers in their ears. They (hide their faces and) wrap their clothes around them (in defiance). They grew obstinate and became (rude and insulting, and) increasingly arrogant.”
So, in this verse of Quran the traits of arrogant people are discussed who become rude when it comes to listen to others. The one who is humble is always a good listener. We may disagree on any matter with our brothers and sisters, but what we should not forget is the behavior of a good muslim.
ALLAH swt says in Quran: 41:34
"And O prophet :goodness and evil are not equal.Repel evil with what is best. You will see that, he with whom you had enemity, has become your closest friend."
This verse gives us a very beautiful lesson to be soft and genetle towards even those who are not good to us. when we work on thr formulaof “tit for tat” we take revenge but we make that person our enemy forever. This is what we can see as a practice in some tribes who are still present in some pasrts of world. They are enemies of each other from egenrations. Instead of forgiving, these people like to grow in enemity.
In another verse of Quran, ALLAh swt says that the one who is rude and harsh, cannot make the people around him understand even his valid points. Such a person is never liked and he can never leave a good impression on the people he live with.
“It was by a sort of mercy from God thou didst deal gently with them, for hadst thou been rough and rude of heart they had dispersed from around thee. But pardon them, and ask forgiveness for them, and take counsel with them in the affair. As for what thou hast resolved, rely upon God; verily, God loves those who do rely.”
There are several ahadith that deal with how Muhammad s.a.w.w dealt with even those who become harsh with HIM, one of them is given below;
Bukhari Volume 3, Book 38, Number 502:
Narrated Abu Huraira: A man came to the Prophet demanding his debts and behaved rudely. The companions of the Prophet intended to harm him, but Allah's Apostle said (to them), "Leave him, for the creditor (i.e. owner of a right) has the right to speak." Allah's Apostle then said, "Give him a camel of the same age as that of his." The people said, "O Allah's Apostle! There is only a camel that is older than his." Allah's Apostle said, "Give (it to) him, for the best amongst you is he who pays the rights of others handsomely."
This is how our beloved prophet s.a.w.w dealt with a man who spoke to Him harshly, ask yourself, if you can be this genetle and nice towards even your friends?
Prophet Muhammad s.a.w.w told us the traits of hypocrite in the following hadith;
Bukhari Volume 1, Book 2, Number 33:
Narrated 'Abdullah bin 'Amr: The Prophet said, "Whoever has the following four (characteristics) will be a pure hypocrite and whoever has one of the following four characteristics will have one characteristic of hypocrisy unless and until he gives it up.
1. Whenever he is entrusted, he betrays.
2. Whenever he speaks, he tells a lie.
3. Whenever he makes a covenant, he proves treacherous.
4. Whenever he quarrels, he behaves in a very imprudent, evil and insulting manner."
To sum up, we should take care of our speech and we should not be arrogant neither in our talk nor in our behavior.
