Would one of you like to eat the flesh of his brother when dead? You would abhor it." And by its meaning in Surat Al-Humazah: "Woe to every slanderer and backbiter." As for slander, it is explicitly mentioned by its word in Surat Al-Qalam: "A great slanderer, going about with calumnies." And by its meaning in Surat At-Tawbah: "They seek to stir up discord among you, and among you are listeners to them."
