‘Islam’ is a command meaning ‘submit’ (by choice or the sword).
The root letters are slm, which can also transform into ‘salaam.’ This word can mean ‘peace’ (and is related to ‘shalom,’ since both Hebrew and Arabic are Semitic languages). However, go to thefreedictionary.com and look up ‘salaam.’ ‘Making salaam’ is specific, and means ‘deference’ or ‘obeisance’ or ‘homage.’ There is a specific practice of bowing and taking the other hand and placing it on the forehead.
Wake me up when it's over.
