I appreciate your intention to foster peaceful cooperation and mutual love amongst the peoples of the world. I respect your desire to inspire a deeper understanding of how humanity should cease dividing, fighting, and waging war.
However, unfortunately, some of your statements are not biblically correct.
The god of Islam is not the same Creator of Christianity. Islam claims that their Allah god has no son.
Thus, we who worship God through His Son Jesus Christ are not brothers and sisters from the same origin as Muslims.
1 John 2:23
Whosoever denieth the Son, the same hath not the Father: he that acknowledgeth the Son hath the Father also.
Quran
Surah An-Nisa Ayat 171
O People of the Scripture, do not commit excess in your religion or say about Allah except the truth. The Messiah, Jesus, the son of Mary, was but a messenger of Allah and His word which He directed to Mary and a soul [created at a command] from Him. So believe in Allah and His messengers. And do not say, "Three"; desist - it is better for you. Indeed, Allah is but one God. Exalted is He above having a son. To Him belongs whatever is in the heavens and whatever is on the earth. And sufficient is Allah as Disposer of affairs.
Quran
Surah Al-Anam Ayat 101
[He is] Originator of the heavens and the earth. How could He have a son when He does not have a companion and He created all things? And He is, of all things, Knowing.
Quran
Surah Al-Ma'idah Ayat 72-75
They have certainly disbelieved who say, "Allah is the Messiah, the son of Mary" while the Messiah has said, "O Children of Israel, worship Allah, my Lord and your Lord." Indeed, he who associates others with Allah - Allah has forbidden him Paradise, and his refuge is the Fire. And there are not for the wrongdoers any helpers.
Quran
Surah At-Taubah Ayat 30
The Jews say, "Ezra is the son of Allah "; and the Christians say, "The Messiah is the son of Allah." That is their statement from their mouths; they imitate the saying of those who disbelieved [before them]. May Allah destroy them; how are they deluded?
