Other Prophecies by Prophet Isaiah (pbuh)

another prophecies are found in isaiah (42:1;4 and11) which suggest very clear ideas about the arabian prophet (pbuh) and the vivid descriptions of arab inhabitants in the following examples; (verse1):  "behold my servant, whom i uphold, my chosen, in whom my soul delights" ;(verse 4): "he will not fail or be discouraged till he has established justice in the earth…" ; (verse 11):  "let the desert and its cities lift up their voice, the villages that kedar inhabits; let the inhabitants of sela sing for joy, let them shout from the top of the mountains. let them give glory to the lord, and declare his praise in the coast-lands." 

by specifying "kedar inhabitants" clearly refers to the arabs (ismaelites) whose prophet came from among them was prophet muhammad (pbuh) and whose message islam that gave complete justice and peace to the people. the religion of submission (islam) was chosen by god himself and conferred the prophethood to muhammad (pbuh) to whom his soul delights. peace which is the meaning of islam religion is the natural result of justice. also, the prophecy mentioned about the coasts-lands that signify those coasts around the arabian peninsula and the mediterranean sea especially along north africa.

 the people who inhabit these places have forgotten their original languages and adopted the language of the qur'an which is pure arabic in reference to (isaiah 29:10-12)
