Majma al-Zawaid — Hadith 13281

Umar bin Sa'd bin Abi Waqqas narrates: I had some business with my father, Sayyiduna Sa'd (may Allah be pleased with him). A narrator named Mujammi' stated that Umar bin Sa'd had some business with his father. Before mentioning his business to his father, he spoke in a manner that later became fashionable among people in those days, which was rhymed and ornate. Sayyiduna Sa'd (may Allah be pleased with him) had not heard such speech before. When he finished speaking, Sayyiduna Sa'd (may Allah be pleased with him) said: "My son, have you finished your speech?" He replied: "Yes." Sayyiduna Sa'd (may Allah be pleased with him) said: "I have never been further from (granting) your need, nor less inclined towards you, than since I heard this speech of yours. I heard the Prophet (peace and blessings be upon him) saying: 'Soon there will be people who will eat by means of their tongues just as a cow eats from the ground.'"
Ahmad and al-Bazzar recorded it through various routes, and its chain contains a narrator who has not been named. The best of them is the one which Ahmad recorded through Zayd bin Aslam from Sayyiduna Sa'd (may Allah be pleased with him), who narrates: The Prophet (peace and blessings be upon him) said: "The Hour will not be established until a people come forth who will eat by means of their tongues just as a cow eats with its tongue." Its narrators are the narrators of the Sahih, except that Zayd bin Aslam did not hear from Sayyiduna Sa'd (may Allah be pleased with him). And Allah knows best.
