The Canadian, Dr. Gary Miller, who converted
1- The Quran is the miracle of Prophet Mohammed – salam be to him; this miracle is still available with us, while the miracles of all the past prophets disappeared with them after their death: like the staff of Moses, the medical miracles of Jesus, etc.
2-The Quran does not mention the name of Prophet Mohammed more than 5 times only, while the name of Jesus Christ was mentioned 25 times, in addition to a large number the names of Moses and the other prophets were mentioned. So if Mohammed invented the Quran as do some claim, then he would mention his name more than others.
3- The daughter and the wives of the prophet are not mentioned in the Quran, while there is a complete soorah (or chapter of the Quran) called the soorah of Mary (mother of the Christ.)
4-None may challenge all people to find any defect and difference from the other heavenly books concerning the monotheism, other than God only may say this.
As in the Quran 4: 82
أَفَلاَ يَتَدَبَّرُونَ الْقُرْآنَ وَلَوْ كَانَ مِنْ عِندِ غَيْرِ اللّهِ لَوَجَدُواْ فِيهِ اخْتِلاَفًا كَثِيرًا
The explanation:
(Will they not ponder the Quran?
If it had been from [anyone] other than God they would have found therein much variation [from the ancient heavenly scriptures, contradicting the monotheism.] )
I say: This is right, while this challenge cannot be said by anyone unless by God Himself: i.e. no one can say this which is in the Quran 17: 88
قُل لَّئِنِ اجْتَمَعَتِ الإِنسُ وَالْجِنُّ عَلَى أَن يَأْتُواْ بِمِثْلِ هَذَا الْقُرْآنِ لاَ يَأْتُونَ بِمِثْلِهِ وَلَوْ كَانَ بَعْضُهُمْ لِبَعْضٍ ظَهِيرًا
The explanation:
(Say [O Mohammed, to these associaters]: "Even though the whole man-kind and genie-kind [: demon-kind] were to gather together in accordance to produce the like of this Quran, they could not produce its like, even if they aided each other with support.")
