Don’t be mean or rude — it’s a waste of energy.

Good manners and noble qualities of mind and character enjoy a place of crucial importance in the structure of Islamic teaching. The Prophet Muhammad (sallahu alihi was salaam) said “I have been sent down by Allah to teach moral virtues and to evolve them to highest perfection.”

What you can do to deal with rude people:

1. Kill them with kindness. Just because someone is incredibly rude to you, it doesn't mean that you have to be rude in return. If you are especially kind to the person being rude to you, it is likely to frustrate him or her, but you will be a good example for those around you. 

2. Take it with a pinch of salt. Don't take it personally. Just remember that the person might have had an incredibly bad day, or simply may be a complete dodo. In either case, you are not the reason for their rudeness.

3. Beware that you may have to repeat yourself.The rude person you are dealing with may get so caught up giving you grief that he or she may not be listening to what you say. This might be especially true if you are trying to help this person through a problem. As a result, you might find yourself having to provide the same information over again.

4. Rudeness can be an opportunity to teach a lesson on manners. A chance, unwelcome brush with rudeness with a supplier, vendor, or customer can be an opportunity to remind your coworkers that manners do matter. Realizing how such behavior comes across to others might just be the impetus needed to reform those who occasionally slip into rude behavior.

In the end, there is simply no need to be rude, especially in the work place.
