Isaiah uses the word Muslim (Isaiah 42:19)

Who is blind, but my servant? or deaf, as my messenger that I sent? who is blind as he that is perfect, and blind as the LORD's servant? (Isaiah 42:19)

Commentary:

Ellicott's Commentary for English Readers

As he that is perfect.—Strictly speaking, the devoted, or surrendered one. The Hebrew meshullam is interesting, as connected with the modern Moslem and Islam, the man resigned to the will of God.

Pulpit Commentary

 As he that is perfect; rather, as he that receives reward from me(see Proverbs 11:31; Proverbs 13:13). The word used is connected etymologically with the Arabic muslim (our "Moslem");

Cambridge Bible for Schools and Colleges

as he that is perfect] R.V. has, “as he that is at peace with me.” The meaning of the Heb. měshullâm (a proper name in 2 Kings 22:3; Ezra 8:16, and often) is uncertain. Many take it as the equivalent of the Arabic “Moslim,” = “the surrendered one” (Cheyne, Comm.). 

George Haydock's Catholic Bible Commentary

Isaiah 42

Sold. Hebrew Cimshullam, (Haydock) the perfect, or favoured. The Turks call "believers" Musselmans.(Calmet)

Keil & Delitzsch Commentary on the Old Testament

Isaiah 42

 but one allied in peace and friendship, the confidant of God. It is the passive of the Arabic muslim, one who trusts in God

E.W. Bullinger's Companion Bible Notes

Isaiah 42

perfect = an intimate friend or trusted one. Hebrew. me"shullam (plural of shalam), to be at peace with. Compare 2 Samuel 20:19. Job 22:21. Psalms 7:4. It is from this word we have Mussulman and Moslem

The People's Bible by Joseph Parker

Isaiah 42

The servant that ought to have seen everything sees nothing; the messenger that ought to have the hearing ear has lost his faculty of hearing; and he that ought to have been perfect is blind. A curious word is this which is rendered "perfect." In sound it is like "Moslem," and it means literally, the resigned man. That is what Moslem affects to be. That is the very genius of Islam, the resigned man; the man who says he will make no effort, because what will be will be; he need not bestir himself in the morning, because he can effect nothing by all his labour and energy; he will resign himself to the rocking of nature, and be lulled to rest by its soothing movement. 

“Submit to God and be at peace with him; in this way prosperity will come to you. (Job 22:21)

“For then I will restore to the peoples pure lips, So that all of them may call on the name of the LORD, To serve Him shoulder to shoulder. (Zephaniah 3:9)
