﴿ وَدَّت طَّآئِفَةٌۭ مِّنْ أَهْلِ ٱلْكِتَٰبِ لَوْ يُضِلُّونَكُمْ وَمَا يُضِلُّونَ إِلَّآ أَنفُسَهُمْ وَمَا يَشْعُرُونَ ﴾
“Some of the followers of earlier revelation would love to lead you astray: yet none do they lead astray but themselves, and perceive it not.”
(A party of the People of the Scripture long to make you go astray�) [3:69]. This was revealed about Mu�adh ibn Jabal and Hudhayfah [ibn al-Yaman] and �Ammar ibn Yasir when the Jews called them to embrace their religion. This story has already been mentioned in Surah the Cow.
