Be very careful if you have not studied the word of God in its fulness.
God is no respecter of persons.
(Isa 60:6) The multitude of camels shall cover thee, the dromedaries of Midian and Ephah; all they from Sheba shall come: they shall bring gold and incense; and they shall shew forth the praises of the Lord.
(Isa 60:7) All the flocks of Kedar shall be gathered together unto thee, the rams of Nebaioth shall minister unto thee: they shall come up with acceptance on mine altar, and I will glorify the house of my glory.
(Isa 60:8) Who [are] these [that] fly as a cloud, and as the doves to their windows?
(Isa 60:9) Surely the isles shall wait for me, and the ships of Tarshish first, to bring thy sons from far, their silver and their gold with them, unto the name of the Lord thy God, and to the Holy One of Israel, because he hath glorified thee.
Many Muslims are the sons of Ismeal the son of Abraham, and God has a place for them in heaven also.
