Question
How can I invite Christians to Islam and debate with them?
Answer
All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and messenger.
The best way to invite a Christian to Islam is to follow the way of the Quran and the Sunnah, which is based on the following:
The Quran came as a confirmation, judgment and witness to what is in the Gospel. Parts of the Gospel that conform to what is in the Quran are correct. Conversely, any discrepancy between the two indicates distortion in the Gospel that is corrected in the Quran. Allaah Says (what means): {And We have revealed to you, [O Muhammad], the Book in truth, confirming that which preceded it of the Scripture and as a criterion over it.}[Quran 5:48]
The miraculous birth of 'Eesa (Jesus) as depicted in the Quran. It states that Allaah created him, as He created Aadam with the word ‘Kun’ (Be). Allaah Says (what means): {Indeed, the example of ‘Eesa (Jesus) to Allaah is like that of Aadam. He created Him from dust; then He said to him, "Be," and he was.}[Quran 3:59]
The true nature of Al-Maseeh (‘Eesa) and his mother Maryam (Mary), may Allaah exalt their mention, as mentioned in the Quran in the Saying of Allaah (which means): {The Maseeh, son of Maryam (Mary), was not but a messenger; [other] messengers have passed on before him. And his mother was a supporter of truth. They both used to eat food.}[Quran 5:75]
Indication of the distortions that occurred in the Gospel and resulted in great differences between the Quran and the Gospel with regards to the nature of 'Eesa and his mother, may Allaah exalt their mention. The occurrence of such distortions is confirmed by the contradictions that exist between various versions of the Gospel.
Allaah Knows best.
