Musnad Ahmad 28:113

'Abd al-Samad narrated to us, Hammad narrated to us, from 'Ata' ibn al-Sa'ib, from his father, from 'Abdullah ibn 'Amr, that the Jews used to say to the Messenger of Allah, may Allah bless him and grant him peace: "Sam (death) be upon you," then they would say to themselves: "Why does Allah not punish us for what we say?" [Al-Mujadilah: 8]. Then this verse was revealed: "And when they come to you, they greet you with a greeting that Allah does not greet you with" [Al-Mujadilah: 8], to the end of the verse.
