Allaah (The Most High) said:

مَّا يَوَدُّ الَّذِينَ كَفَرُوا مِنْ أَهْلِ الْكِتَابِ وَلَا الْمُشْرِكِينَ أَن يُنَزَّلَ عَلَيْكُم مِّنْ خَيْرٍ مِّن رَّبِّكُمْ ۗ وَاللَّهُ يَخْتَصُّ بِرَحْمَتِهِ مَن يَشَاءُ ۚ وَاللَّهُ ذُو الْفَضْلِ الْعَظِيمِ

Neither those who disbelieve among the people of the Scripture nor Al-Mushrikun (the disbelievers in the Oneness of Allah, idolaters, polytheists, pagans, etc.) like that there should be sent down unto you any good from your Lord. But Allah chooses for His Mercy whom He wills. And Allah is the Owner of Great Bounty.

Reminders from Imaam Sadi (rahimahullaah)

They do not want good to be sent down unto the Muslims from their Lord-be it little or plentiful-out of envy and enmity; however Allaah chooses for His Bounty and He is the Owner of Great Bounty. And from Allaah’s Bounties bestowed upon the Muslims is that He sent down the Qur’aan unto the Messenger (sallal-laahu-alayhi-wasallam) in order to sanctify the Muslims, and teach them the Book (the Qur’an) and the Hikmah (i.e. authentic Sunnah, Islamic laws and Fiqh – jurisprudence), and teach them that which they did not used to know.
