Al-Matalib al-'Aliyah 3586 — Surah al-Ma'idah

It is narrated from Sayyiduna Jabir (may Allah be pleased with him) concerning the words of Allah, the Blessed and Exalted, "avid listeners to falsehood" [Surah al-Ma'idah: 41], that he said: "This means the Jews of Madinah"; and concerning the words of the Exalted Lord, "listening for another people who have not come to you" [Surah al-Ma'idah: 41], he said: "This means the people of Fadak, who had not come to you (peace and blessings be upon him)," and this (explanation) runs to the end of the verse.
Imam al-Humaydi transmitted this report in his Musnad through Sufyan bin Uyaynah; it explains the background of this verse of the Noble Qur'an: how the Jews were fond of false talk and were acting as spies for those people (the people of Fadak) who did not themselves come to his (peace and blessings be upon him) gathering.
