The ruling on the person who greets

Q 1, 2: some people greet each other saying: "Good Morning" or "Good Afternoon" and the response is" Bright Morning" or "Bright Afternoon". Others use the greeting, "Peace! O men", and abandon the Sunnah which is "As-Salam `Alaikum wa Rahmatullahi wa barakatuh (Peace, mercy and blessing of Allah be upon you)". I drew their attention to this mistake, but they were not convinced. On the contrary, they insist on exchanging these greetings in Bishah, Hijaz in the south of Al-Ta'if to Abha, Qahtan and Yanbu`.

A 1, 2: The Islamic greeting is, "As-Salam `Alaikum [Peace be upon you]" and if a person adds "Wa Rahmatullahi", i.e. Allah's mercy, it will be better and if he adds "Wa Barakatuh", i.e. and His blessings, he will receive the most perfect reward.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
