Surah Al-Baqarah — Ayah 89 (2:89)
وَلَمَّا جَآءَهُمۡ كِتَٰبٞ مِّنۡ عِندِ ٱللَّهِ مُصَدِّقٞ لِّمَا مَعَهُمۡ وَكَانُواْ مِن قَبۡلُ يَسۡتَفۡتِحُونَ عَلَى ٱلَّذِينَ كَفَرُواْ فَلَمَّا جَآءَهُم مَّا عَرَفُواْ كَفَرُواْ بِهِۦۚ فَلَعۡنَةُ ٱللَّهِ عَلَى ٱلۡكَٰفِرِينَ ٨٩
English translation (Saheeh International)
And when there came to them a Book [i.e., the Qur’ān] from Allāh confirming that which was with them - although before they used to pray for victory against those who disbelieved - but [then] when there came to them that which they recognized, they disbelieved in it; so the curse of Allāh will be upon the disbelievers.
Brief commentary
The Qur’ān came to them from Allah, agreeing with the universal true principles of the Torah and the Gospel. Before it was revealed, they used to say that they would be helped against the idolaters, who worship others alongside Allah, and would have success over them when a prophet was sent, since they would have faith in him and follow him. But when the Qur’ān and Muhammad (peace be upon him) came to them, according to the description they recognised and the truth they knew, they disbelieved him. Allah curses those who disbelieve Him and His Prophet.
