(And when the son of Maryam is quoted as an example, behold, your people cry aloud thereat.) Several others narrated that Ibn `Abbas, may Allah be pleased with him, Mujahid, `Ikrimah, As-Suddi and Ad-Dahhak said, "They laughed, i.e., they were astounded by that." Qatadah said, "They were repelled by that and they laughed." Ibrahim An-Nakha`i said, "They turned away." The reason for this was mentioned by Muhammad bin Ishaq in As-Sirah. He said, "According to what I have heard, the Messenger of Allah ﷺ sat down one day with Al-Walid bin Al-Mughirah in the Masjid, and An-Nadr bin Al-Harith came and sat down with them. There were also other men from the Quraysh in the gathering. The Messenger of Allah ﷺ spoke, then An-Nadr bin Al-Harith came up to him and the Messenger of Allah spoke to him until he defeated him in argument. Then he recited to him and to them,
وَلِأُبَيِّنَ لَكُم بَعْضَ الَّذِي تَخْتَلِفُونَ فِيهِ (and to explain to you some of those matters in which you differ...43:63) Since Bana Isra'il were drowned in arrogance and obstinacy, they had tampered with the Divine laws. Sayyidna ` Isa (علیہ السلام) disclosed the reality of such distortions. The words 'some matters' are used because some other matters were purely of mundane nature. He might have not felt the need to deal with those differences. (Bayan-ul-Qur an).
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 65–72
Here ‘wisdom’ means the spirit of religion and ‘straight path’ means the upholding of the virtues that are mentioned in the verse, namely, fear and worship of God, prayer to Him and obedience to the Prophet. This is the real religion. What the Jews did at a later stage was to lose the spirit of religion and indulge in hair-splitting over the basic principles of religion. Due to these totally contrived additions, differing sects developed among them. One sect laid stress on one controversial issue, another laid stress elsewhere. In this way, with them, one religion turned into several religions. Jesus Christ was sent to the Jews to tell them that the really important aspect of religion was its spirit and not form; and also to inform them that they would achieve salvation on following the true religion sent by God and not that religion which they had themselves devised. Jesus told them that the real religion was based on the fear of God, and that they should become worshippers of the one and only God and follow the example of the Prophet in everyday affairs. Beyond this, whatever innumerable problems they had created by their futile discussions and hair-splitting arguments were their own self-made additions. They were advised to give up all these additions and be steadfast in their adherence to the real religion. All these exhortations made by Jesus exist in the Bible even today.
