For a Muslim to greet their colleagues

Q 1: what is the ruling on greeting Muslims saying: "Al-Salamu `Ala Man Ittaba`a Al-Huda (Peace be upon those who follow (Part No. 24; Page No. 115) the guidance)"?

A: It is best to greet fellow Muslims saying: "Al-Salamu `Alaikum (peace be upon you)" or "Al-Salamu `Alaikum wa Rahmatullahi wa Barakatuh (Peace, Mercy and Blessings of Allah be upon you)". Do not say: "Salamun `Ala Man Ittaba`a Al-Huda (peace be upon those who follow the guidance)" unless you are greeting a non-Muslim or a mixed group of Muslims and non-Muslims. Greeting a Muslim in this manner may seem offensive and may raise ill-thoughts.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
