السلام عليكم pronounced as As-Salam-u-Alikum.
Salaam
I don't say anything because I am not a Muslim. Muslims say "peace be upon him". I have heard anti-Muslims say much ruder things, but I find this unnecessarily insulting. After mentioning the name the holy Prophets the Muslims say, e.g.: Hazrat Abraham (AS- Alai-his-salam or May peace be upon him) After the name of Hazrat Muhammad the Muslims say Sallal la ho alai wasallam or may say the May peace be upon him. The Muslims must respect all the holy Prophets (May peace be upon them all). It is obligatory on them.
They say صلي الله عليه وسلم which means peace be upon him.
Because it is compulsory for all Muslims to say that whenever the Prophet Muhammad (Peace be upon Him's) name is mentioned. it is for respect.
Jewish viewAs a greeting, we say "Shalom Alechem" when we meet people such as friends and fellow Jews. This does mean Peace be upon you. But we don't use it in reference to prophets, as Muslims do. They say "Mohammad (PBUH)" which means Peace be upon him or Praise be upon him. Muslim viewMuslims greet each other by saying "assalmu aleikom" that means peace upon you or they simply say "salam" that means peace. Jews say "Shalom Alechem" that means also peace upon you or they simply say "shalom" that means also peace. So, both Muslims and Jews say same words but in Arabic and Hebrew; respectively.
If you mean to count the years, Muslims often calculate years after the Hijra; years after the Hijra are labelled AH. For calculations, please note that the Islamic year is about 11 days shorter than the regular year. If you mean what do Muslims say after speaking the name of "Muhammad", the most often thing that they say in Arabic is Rasul Allah 3alayhi salaam (رسول الله عليه سلام) which means "Messenger of God, peace be upon him". In English, they simply say "Peace be upon him".
Jesus said this when he appeared to the disciples after the Resurrection. Jews and Muslims say it frequently - as 'Shalom'or 'Salaam'.
In Pakistan the Muslims uses the Arabic greating to say Hello! "Assalam-u-alaikum." which lit. means 'Peace be upon you.'
'Peace be upon you' More accepted response: 'walaikum assalam' = 'May peace be with you also'
Peace be upon him is a phrase that Muslims often say after saying (or hearing) the name of a prophet of Islam.
This is a tad racist as not all of the Muslims are violent. The extremist Muslims who bilieve that they need to fight in order to defend there religion , are the bad ones. they are not considered as real Muslims Muslims belive in peace they belive in nonviolence
Adam (peace be upon him)
There are approximately 1.8 Billion Muslims in the world. Peace.
