There are some patterns of speech which became a custom in every society. This is a common language all people speak. Like saying "Good Morning" when they get up in the morning or when they meet in the evening saying "good evening", when they are about to go to bed at night saying "good night, sleep tight", when they are eating saying "good appetite", when one is ill saying "get well soon", when one is doing something saying" more power to you", when one sneezes saying "bless you"…
Almost everyone gets adapted to these patterns he sees in the society ever since his childhood. However when one is saying these words, he should not forget that Allah is the Only Power that would enable all these good wishes.
And that is where the difference of a Muslim is seen. A Muslim behaves consciously in every step he takes, in every word he says, in every thought in his mind. He never forgets that every incident he has ever experienced all his life has happened by the Wish of our Lord. It is only the Almighty Allah Who will enable a person to have a good day or a good night, Who will cure him and make him healthy, Who will give him peace and comfort in his sleep, Who will make the food he eats delicious and beneficial or Who will ease and finalize the work he does.
Apart from this it is our Lord Whom a Muslim loves with the most profound and intense love, with the highest devotion and Whom he is most loyal to. He might forget many people he loves, many incidents or many objects from time time. But his love for Allah is so strong that he lives in the awareness of the existence, power, love, friendship, compassion and justice of our Lord in every minute, every single second of his 24 hours. There is not even a single moment that the existence and dominion of Allah is not in his mind.
And for Muslim to commemorate Allah, mentioning and exalting Allah is a very big act of worship. It is at the same time one of the blessings that a Muslim's soul finds most pleasure in. For that reason he would want to commemorate Allah, to exalt His Name, to praise Him by mentioning His greatness in every possibility he gets. A Muslim wants to mention his love for Allah, his devotion, his submission in every turn of phrase in the form of a prayer.
Consequently, a Muslim's way of daily talking is very different from other people just like all his demeanors and attitudes are. A Muslim puts the fact that it is Allah Who will create that act, into words in every speech he makes. In every good will expression, he verbalizes the fact that he wishes those blessings from Allah. For instance instead of using phrases like "Good Morning", "Good Night", "Good Evening", "Sleep tight", "Good Appetite", "Get well soon", "More power to you", "Bless you", he mentions the Name of our Almighty Lord Who will be creating all these wishes by saying "May Allah give you a nice day", "May Allah give you a nice night", "May Allah give you a good evening," "May Allah give you a nice sleep", "May Allah bless you a good appetite", "May Allah cure your illness," "May Allah ease your work", "May Allah bless you a long life".
Apart from this, when someone says his good wishes with the remembrance of Allah's name, he again responds by showing the same awareness in faith. For instance
when someone says "May Allah give you a nice day", he doesn't respond by only saying "to you too". He commemorates and exalts Allah's Name and praises our Lord. He responds by saying "May Allah give you a nice day too". Or in responding to a Muslim who says "May Allah give you good night", he does not respond only by saying "To you too" –Allah is beyond that- He responds by saying "May Allah give you a good night too". He would not use such a wording without mentioning Allah's name even if he was thinking about Allah in that moment. He doesn't find it becoming to the love, devotion friendship he feels for Allah to assume even a slightest defect in his wordings.
This stems from the good morality of the Muslim. In his conscience he cannot bring himself to talk about an incident he knows that Allah will create, without mentioning His name. No matter what the wording the other person uses is, his response will definitely be by mentioning Allah's name and by exalting our Lord.
... and certainly the remembrance of Allah is the greatest, and Allah knows what you do. (Surat Al-Ankabut: 45)
To Allah belong the Most Beautiful Names, so call on Him by them and abandon those who desecrate His Names. They will be repaid for what they did. (Surat Al-A'raf: 180)
