A. Regarding Sonship of Jesus:That is Jesus, son of Mary, in word of truth, concerning which they are doubting. It is not for Allah to take a son unto Him. Glory be to Him! When He decrees a thing he but says to it "Be", and it is. (Qur'an 19:34,35).
And they say, 'The All-merciful has taken unto Himself a son.' You have indeed advanced something hideous. The heavens are well nigh rent of it and the earth split asunder, and the mountains well nigh fall down crashing for that they have attributed to the All-Merciful a son; and it behoves not the All-Merciful to take a son. None is there in the heavens and earth but comes to the All-Merciful as a servant (Qur'an 19:88-93).
Truly the likeness of Jesus, in Allah's sight, is as Adam's likeness; He created him of dust, then said He unto him, "Be", and he was. (Qur'an 3:59).
People of the Book, go not beyond the bounds in your religion, and say not as to Allah but the Truth. The Messiah, Jesus, son of Mary, was only the Messenger of Allah, and His Word that He committed to Mary, and a spirit from Him. So believe in Allah and His Messengers. and say not, 'Three', Refrain, better is it for you. Allah is only One Allah. Glory be on Him - that He should have a son! To Him belongs that which is in the heavens and on the earth, Allah suffices for a guardian. (Qur'an 4:171)
B. Regarding Jesus being Allah:And when Allah said. 'O Jesus son of Mary,did you say unto men, "Take me and my mother as Allahs, apart from Allah?" He Said, 'To You be Glory! It is not mine to say what I have no right to. If I indeed said it, You knew it, knowing what is within my soul, and I do not know what is within Your soul; You know the things unseen. I only said to them what You did command me: "Serve Allah, my Lord and your Lord." And I was a witness over them, while I remained among them; but when You did take me to Yourself the Watcher over them; You are the witness of everything. (Quran 5:116,117)
C. Regarding Crucifiction of Jesus:And for their unbelief, and their uttering against Mary a mighty calumny, and for their saying, 'We slew the Messiah, Jesus son of Mary, the Messenger of Allah'...yet they did not slay him, neither crucified him, only a likeness of that was shown to them. Those who are at variance concerning him surely are in doubt regarding him, they have no knowledge of him, except the following of surmise; and they did not slay him of certainty... no indeed, Allah raised him up to Him; Allah is Almighty, All-Wise. There is not one of the people of the Book but will assuredly believe in him before his death, and on the Resurrection Day he will be a witness against them. (Qur'an 4:156-159).
Finally, ask Allah pardon and forgiveness and emancipation from the fire
