They say صلي الله عليه وسلم which means peace be upon him.
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.
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.

they say salla al alayhi wa selam ...(may the peace and blessings of Allah be upon him) Allah is God.

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.
It is not Hazrat Muhammad (SAW) only whom the Muslim say God bless him. The Muslims pray for all the prophets of Almighty Allah. They also believe in all the prophets (May Allah bless them all).
