They are those whom Allah has cursed, and he whom Allah curses, you will not find for him (any) helper.This Ayah (4:52) contains a curse for the Jews and informs them that they have no supporter in this life or the Hereafter, because they sought the help of the idolators.They uttered this statement (in Ayah 4:51) to lure the disbelievers into supporting them, and they ultimately gathered their forces for the battle of Al-Ahzab, forcing the Prophet and his Companions to dig a defensive tunnel around Al-Madinah. But, Allah saved the Muslims from their evil,وَرَدَّ اللَّهُ الَّذِينَ كَفَرُواْ بِغَيْظِهِمْ لَمْ يَنَالُواْ خَيْراً وَكَفَى اللَّهُ الْمُوْمِنِينَ الْقِتَالَ وَكَانَ اللَّهُ قَوِيّاً عَزِيزاًAnd Allah drove back those who disbelieved in their rage, they gained no advantage (booty). Allah sufficed for the believers in the fighting. And Allah is Ever All-Strong, All-Mighty. (33:25)
