23. If the Qur’an came down from the “Lord of the Worlds” and was ratified by a group of demons would this be a good sign that it came from God?

the Bible No
Yes the Quran

the Bible's Perspective

John 14:30I will no more speak much with you, for the prince of the world comes, and he has nothing in me.
2 Corinthians 4:3—4Even if our Good News is veiled, it is veiled in those who are dying,

the Quran's Perspective

Al-Fatiha (The Opener) 1:2Praise be to Allah, Lord of the Worlds,
Yunus (Jonah) 10:37And this Qur'an is not such as could ever be invented in despite of Allah; but it is a confirmation of that which was before it and an exposition of that which is decreed for mankind - Therein is no doubt - from the Lord of the Worlds.
Al-Ahqaf (The Sand Dunes) 46:29-30And when We inclined toward thee (Muhammad) certain of the jinn, who wished to hear the Qur'an and, when they were in its presence, said: Give ear! and, when it was finished, turned back to their people, warning. They said: O our people! Lo! we have heard a scripture which hath been revealed after Moses, confirming that which was before it, guiding unto the truth and a right road.
Al-Jinn (The Jinn) 72:1-14Say (O Muhammad): It is revealed unto me that a company of the Jinn gave ear, and they said: Lo! we have heard a marvellous Qur'an, Which guideth unto righteousness, so we believe in it and we ascribe no partner unto our Lord. And (we believe) that He - exalted be the glory of our Lord! - hath taken neither wife nor son, And that the foolish one among us used to speak concerning Allah an atrocious lie. And lo! we had supposed that humankind and jinn would not speak a lie concerning Allah - And indeed (O Muhammad) individuals of humankind used to invoke the protection of individuals of the jinn, so that they increased them in revolt against Allah); And indeed they supposed, even as ye suppose, that Allah would not raise anyone (from the dead) - And (the Jinn who had listened to the Qur'an said): We had sought the heaven but had found it filled with strong warders and meteors. And we used to sit on places (high) therein to listen. But he who listeneth now findeth a flame in wait for him; And we know not whether harm is boded unto all who are in the earth, or whether their Lord intendeth guidance for them. And among us there are righteous folk and among us there are far from that. We are sects having different rules. And we know that we cannot escape from Allah in the earth, nor can we escape by flight. And when we heard the guidance, we believed therein, and whoso believeth in his Lord, he feareth neither loss nor oppression. And there are among us some who have surrendered (to Allah) and there are among us some who are unjust. And whoso hath surrendered to Allah, such have taken the right path purposefully.
