سورة القلم

Ali ibn Ibrahim (may Allah have mercy on him): هَمَّازٍ مَشَّاءٍ بِنَمِیمٍ [Defamer, going about with slander] was one who carried tales against the Messenger of Allah (peace be upon him and his family) and incited his companions against him.

Imam Sadiq (peace be upon him): Three groups will not enter Paradise: one who sheds another's blood, the drinker of wine, and the tale-bearer.

The Messenger of Allah (peace be upon him and his family): Abdullah ibn Sinan said: The Messenger of Allah (peace be upon him and his family) said: "Shall I not inform you of the worst among you?" They said: "Yes, O Messenger of Allah (peace be upon him and his family)!" He said: "Indeed, they are those who tread the path of tale-bearing, and separate loved ones from one another, and seek out faults in the pure and innocent."

The Messenger of Allah (peace be upon him and his family): O Ali (peace be upon him), ten groups from this ummah have disbelieved in Allah the Great ... the fault-finders, and the one who stirs up sedition.
