Al-Matalib al-'Aliyah 2663 — Censure of tale-bearing

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that Sayyiduna Umar al-Faruq (may Allah be pleased with him) said: "The worst of people are of three kinds: first, a man who acts arrogantly towards his parents and humiliates and belittles them; second, a man who strives to create discord between a man and his wife, and in this matter wrongfully supports the man against his wife until he causes them to separate, and then afterwards marries that woman himself; and third, a man who strives to spread corruption among people through lies until they become enemies of one another and harbour hatred and enmity towards each other."
The chain of this athar (report) contains Musa bin Ubaydah al-Rabadhi, a weak narrator, for which reason this narration is weak in its chain.
