Why Muslims must avoid Backbiting and Gossip
Praise be to Allah.
The Muslim has to guard his tongue and avoid things that have been forbidden. Among these forbidden things which people often take lightly are gheebah (backbiting), buhtan (slander) and nameemah (malicious gossip).
Gheebah or backbiting means speaking about a Muslim in his absence and saying things that he would not like to have spread around or mentioned. Buhtan or slander means saying things about a Muslim that are not true, or in other words telling lies about him. Nameemah or malicious gossip means telling one person what another said in order to cause trouble between them.
There is a great deal of evidence to show that these actions are haram (impermissible). It will suffice for us to mention just a few of them in order to demonstrate that they are haram.
Allah says (interpretation of the meaning): “neither backbite one another. Would one of you like to eat the flesh of his dead brother? You would hate it (so hate backbiting). And fear Allah. Verily, Allah is the One Who forgives and accepts repentance, Most Merciful” (Q49:12)
It was narrated from Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (PBUH) said: “Do you know what gheebah (backbiting) is?” They said, “Allah and His Messenger know best.” He said, “Saying something about your brother that he dislikes.” It was said, “What if what I say about my brother is true?” He said, “If what you say is true then you have backbitten about him, and if it is not true, then you have slandered him.” [Muslim].
