A Muslim always submits/commits to Allah and he trusts him for ensuring peace, besides being grateful for his mercy on the mankind. Islam and Muslim have trilateral root words i.e. Salam, Taslim and Aslama, all means the ‘submission’ as well as peace.
“… if they remove themselves from you and do not fight you and offer you peace (l-Salama) ….”
The words “Aslama, Tasliman, Islam”, leads to acceptance based on trust or faith, acknowledging a relationship of peace and friendship rather than hostility. Taslim is another word of greeting used in the backdrop of acceptance, or submission or peace depending upon the context. In the context of Allah the word that initially meant acceptance, becomes submission or surrender.
The common root word for a greeting such as Salam and submission to God such as Islam/Muslim is also found in other religions and cultures. For example, Namaste is a greeting while namaha from the same root word means submission to God. Namaste is combination of two words Namah (नम:) + Te (ते, means ‘I bow down to you’ or ‘Obeisance to you’. In fact, Namaste is the Sanskrit equivalent of Salam.
In real sense, the word Muslim denotes to every true believer: whether he follows Islam, Christianity, Hinduism, Judaism etc., but who is committed to the Almighty rather than an adherent of a particular religion. “And strive in His cause as ye ought to strive, (with sincerity and under discipline).” (22:78) & “We believe therein, for it is the Truth from our Lord: indeed we have been Muslims (bowing to Allah´s Will) from before this.” (29:53)
Jesus said, “We are Allah´s helpers: We believe in Allah, and do thou bear witness that we are Muslims”. (3:52) & “We have faith, and do thou bear witness that we bow to Allah as Muslims´”. (5:111)
The Prayer of Abraham, “Behold! his Lord said to him: “Bow (thy will to Me)” I bow (my will) (aslamtu) to the Lord and Cherisher of the Universe.” (131)
A Muslim is one who believes in all the prophets as Messengers of Allah and believes in all the scriptures as the revelations from Allah. He is also not a sectarian. In some, he is a person committed to peace, humanity, harmony, besides being in spiritual connect with the Almighty.
