[Ali Imran]

The book of Isaiah is filled with sobering accounts of Israel's sin and rebellion and warnings of their coming judgement. But along with warnings, Isaiah also offers a message of hope—a suffering servant, a Messiah, will come to establish God's Kingdom on Earth and create a new Jerusalem.

Yet a moslem claims it’s their muh lol

No one else fit the clues given.

1. A prophet sent to the people of Kedar, ie. the Arabs
2. Sent to a people who were worshipping idols.
3. He will come with a justice system for the gentiles.
4. He will bring joy to the people of Sela.

All that fits Prophet Muhammad صلي الله عليه وسلم like a glove.
