These are the Children of Israel who plotted against Jesus as did they against Prophet Muhammad. We have the Zionist, Jewish campaign aimed at defaming Islam. They claim to have had been terrorized at the time of the Prophet, but in reality, they were the ones who denied and disbelieved in the signs of the Almighty and plotted to kill Prophet Muhammad (saws); so did they against the prophet Issa (PBUH). This is a proof that the people who claim to be chosen by Allah (swt) are a mere plague for humanity:

{ لُعِنَ الَّذِينَ كَفَرُوا مِن بَنِي إِسْرَائِيلَ عَلَىٰ لِسَانِ دَاوُودَ وَعِيسَى ابْنِ مَرْيَمَ ۚ ذَٰلِكَ بِمَا عَصَوا وَّكَانُوا يَعْتَدُونَ}

(Cursed were those who disbelieved among the Children of Israel by the tongue of David and of Jesus, the son of Mary. That was because they disobeyed and [habitually] transgressed.) (Al-Maaida: 78)

(… وَمَكَرُوا وَمَكَرَ اللَّهُ …) (…And the disbelievers planned, but Allah planned …): They plotted in secrecy.

( وَاللَّهُ خَيْرُ الْمَاكِرِينَ … ) (…And Allah is the best of planners): This is not among the attributes of the Almighty because such attributes are kept as revealed by Gabriel (PBUH) to Prophet Muhammad (saws). Therefore, what’s meant here is that the Almighty has undone their plans. Thus, He undoes the bad by the good; and that’s what’s meant here.
