In The Name of Allah, The Most Merciful, The Bestrower of Mercy.

Al-Allamah Salih Al-Fawzan, may Allah protect him, stated:

‏Namīmah: it is to transmit speech among the people in way to cause corruption between them. Allah, Glorified be He, free from all imperfections, the Most High, said:

‏وَلا تُطِعْ كُلَّ حَلافٍ مَّهِينٍ، هَمَّازٍ مَّشَّاءٍ بِنَمِيمٍ‏

And obey not everyone who swears much, and is considered worthless, a slanderer, going about with calumnies. [Al-Qalam 10-11]

The most severe (or serious) in all of this is the one who spreads (tales) among the students of knowledge and the callers to the path of Allah in order to corrupt (their relationships), split the Jama’ah of the Muslims, and in order that some harbour enmity towards others. The one who does this is a tale-carrier and indeed Allah has forbidden believing or obeying such a person, even if he makes an oath, as He (Allah) said:

‏وَلا تُطِعْ كُلَّ حَلاّفٍ مَّهِينٍ، هَمَّازٍ مَّشَّاءٍ بِنَمِيمٍ‏

And obey not everyone who swears much, and is considered worthless, a slanderer, going about with calumnies. [Al-Qalam 10-11]
