Bible: No Qur'an: Yes

Matthew 7:15-20 – 15 Beware of false prophets... 16 wherefore, by their fruits ye shall know them.

John 8:44-49 – 44. Jesus... Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him... 46. Which of you convicteth me of sin?

An-Nahl 16:98 – When you recite the Qur’an seek refuge in Allah from Satan the accursed.

Saba 34:8 & 46 – 8. Has he invented a lie concerning against Allah, or is there in him a madness (inspired by a demon)?” Say (unto them o Muhammad)… 46. There is no madness in your comrade.

At-Takwir 81:22 & 25 – 22. No, your companion (the prophet) is not mad… 25. Nor is this (the Qur’an) the utterance of an accursed Satan.

Note: Muhammad often denied he was demon possessed: 15:6-7, 23:70, 37:36, 44:14, 51:50-52, 68:51. God and Allah
