A person who greets people saying:

Q 3: It is customary in Egypt to greet each other in the morning saying: "Good morning". What is the ruling on this salutation?

A: The Salam (Islamic greeting of peace) is: "Al-Salamu `Alaikum (peace be upon you)". If one adds "Wa rahmatullahi wa barakatuh (and the Mercy and Blessings of Allah be upon you, too)", it is better. After saying that, if a Muslim greets others by saying "Good morning" for example, there is no harm. However, if a Muslim only says "Good morning" without saying: "Al-Salamu `Alaikum", they are mistaken. (Part No. 24; Page No. 120) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
