Surah 2. Al-Baqara
Ayah 97 - 98
97قُلْ مَن كَانَ عَدُوًّا لِّجِبْرِيلَ فَإِنَّهُۥ نَزَّلَهُۥ عَلَىٰ قَلْبِكَ بِإِذْنِ ٱللَّهِ مُصَدِّقًا لِّمَا بَيْنَ يَدَيْهِ وَهُدًى وَبُشْرَىٰ لِلْمُؤْمِنِينَ
98مَن كَانَ عَدُوًّا لِّلَّهِ وَمَلَـٰٓئِكَتِهِۦ وَرُسُلِهِۦ وَجِبْرِيلَ وَمِيكَىٰلَ فَإِنَّ ٱللَّهَ عَدُوٌّ لِّلْكَـٰفِرِينَ
[97-98] Say to them, "Whoever is enemy to Gabriel,100 should understand that he has, by Allah's command, revealed to your heart the Qur'an101 which confirms what was revealed before it,102 and brings Guidance and glad tidings103 to the Believers. (If their enmity to Gabriel is due to this, let them understand that) whoever is enemy to Allah, His Angels, His Messengers, Gabriel and Michael, Allah is enemy to such disbelievers."
100The Jews not only reviled Muhammad (Allah's peace be upon him) and the believers, but also spoke abusively of Gabriel, the chosen Divine Messenger. They said. "He is our enemy: He is not an angel of blessings but of affliction. "
101As Gabriel revealed the Qur'an to Muhammad (Allah's peace be upon him) by Allah's Command, so by abusing Gabriel they actually abused Allah.
102That is, "You abuse Gabriel for no other reason than that he has brought down the Qur'an, whereas the Qur'an confirms the teachings of the Torah; so, in a way, you abuse the Torah as well.
103In the preceding verses, the Jews have been warned of the consequences of their attitude towards the Qur'an and the mission of the Holy Prophet. In this part of the verse, they have been admonished to consider the matter from another point of view. As the Qur'an shows the way to right guidance and brings good tidings to the believers, it is sheer folly to oppose it and reject it. Thus ney harm none but themselves by depriving themselves of the true success which follows its acceptance.
