Adab
The most important criteria to judge a civilization and culture is the philosophy of the way of life it adopts for guidance in its activities and its attitude towards the realities of life. Islam is not , merely a faith but a way of life, a system ordering and organizing the society. Islam is the natural and normal religion for all time to come. Its principles can and have met successfully challenges that may confront the human society. It is basically a religion of peace, equality and fraternity that preaches love and brotherliness in an easy to follow way.
Western civilization has failed to solve human problems. It has not only failed but landed its adherents into chaos, crime and waywardness with no mental peace. The social and economic problems still remain.
Islam is the only solution as it’s a religion from Allah who created one and all. The one who is all Wise, Powerful, Mighty and Majestic has laid down a system that if adhered to will bring about ultimate prosperity, peace of mind and a society with character and values. This way was practically demonstrated by his beloved Muhammad (salalaahu alaihi wasallam) and when his companions followed in his path, the world saw an enormous change from the depths of darkness they were in to a  very  spiritual, social world that brought true peace of heart and mind to those who upheld it.
Adab in Islam
The word Adab is a very comprehensive word that doesn`t truly have a proper English equivalent. Maybe the word closest in meaning may be etiquette but that still doesn`t do justice to the word. In some dictionaries the word etiquette is defined as a conventional code of conduct.(Collins)
In Arabic dictionaries, the word Adab literally mean an invitation to a meal that has many people and different types of food.
However Ulema explain that Adab is such a thing that has many and an  excess in good things.
The religion of Islam has rules and Adab and a moral code involving every aspect of our lives. This is applicable to the entire of society the young, the elderly, the males and females.
Whatever is sought by a man from the Adab of Islam should be sought by women as well. Women also have to live Islamic lives, therefore it is also important for them to learn and put into practice as well.The Prophet (salalaahu alaihi wa sallam said, Certainly the women are a counterpart of men.(Abu Dawood 236) Whatever a man seeks from the Adab  of Islam should also be sought from the woman,so that both male and female can become complete Muslim.Islam will be presented by both  and be recognised from both as well.
The Adab in which Islam encourages, it is to complete a Muslim and foster a harmonious environment amongst people. There is no doubt that adorning oneself with adab enhances the beauty and way of a Muslim, and he becomes closer to the hearts of people.
Imam Al Qarafi  said,  “ Know very well that a little amount of Adab is better that plenty of Amal (good deeds).”
Ruwaim a pious Aalim once said to his son, “Oh my son make your deeds salt and your Adab flour.” (Min Adabil Islam pg. 5) He means make your Adab plentiful, just as flour is made more than salt when making dough.
After having understood what Adab is and the need for it in the lives of humanity now more than ever. Steps definitely need to be taken to inculcate Adab into our lives.
Steps to take to inculcate good etiquettes :

• Understand the importance of good Adab as a Muslim
• Sit in the gatherings of the Ulema where these Adab are discussed
• Read books related to good Adab.eg Adabul Mufrad of Imam Bukhari,Riyaadus Saaliheen, The sublime conduct of Nabi (salalaahu alaihi wasallam),Shammail Tirmizi.etc.
• Have good friends that will encourage good Adab and stay away from bad company.
• Don’t be afraid of change.  Change for the better.

 
The Deen all of it is ADAB.
