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".
Peace be upon him.
they have to say salat
No; Jews pray to God, creator of the universe. Muhammad is associated with Islam, not with Judaism. Judaism has no connection to Muhammad and does not have an official religious position on him other than him not being a prophet. Note that Muslims also do not pray to Muhammad. Muslims pray to Allah (using the Qur'an which they say that Muhammad revealed).
Hi a simple answer Shiites say: Prophet Muhammad has chosen Ali as his successor, but Sunnis say that has not happened.
They say صلي الله عليه وسلم which means peace be upon him.
there are more than one million Muslims named Muhammad.
Muslims love and revere Prophet Muhammad, God bless him and grant him peace.
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.
