The Jews, as they killed the Prophets, had enmity towards the angels. So, they concealed their animosity towards Jibril, the angel who came down with the revelation of the Holy Qur’an, and said: “Verily, Jibril is our enemy.”
One of the Jewish Rabbis had asked the Prophet r regarding the one who had come to him with the revelation. So, he r answered, “Jibril”. Then the Jewish Rabbi said, “If it had been other than him, we would believe in you. This is because, Jibril is our enemy, as he always comes down (bringing tidings) of earthquakes and punishments. However, Mikail always comes down with mercy, rain and fertility.”
This emphasizes the materialism of the Jews, as they measure affairs based on the human beings’ interests. Thus, their statement that Mikail u is their beloved and Jibril u is their enemy, is due to this materialism that has become their nature.
So, Allah U said to His Prophet , They have enmity towards Jibril because he had brought the revelation upon your heart by permission of Allah. This revelation confirms that which was with them of the Torah, and it is a guidance and good tiding for the believers. Hence, their enmity towards Jibril u is an enmity towards Allah.
