The Book of Asceticism · Hadith 11 (#Ḥadīth #8)
Chapter 1 | On silence Except when Speaking what is Good, Abandonment of what does not concern one, and Slander
النضر بن سويد عن عبد الله بن سنان قال: قال رسول الله صلى الله وآله: الا أخبركم بشراركم؟ قالوا بلى يا رسول الله قال المشاؤن بالنميمة والمفرقون بين الأحبة والباغون للبراء العيب.
8.Al-Naḍr ibn Suwayd narrated from ʿAbdullāh ibn Sinān who said,[1] “The Messenger of Allah (ṣ) said, ‘Should I not inform you about the most vile among you?’ They said, ‘Yes, O Messenger of Allah!’ He said, ‘[They are] those who go about spreading slander [and gossip], those who cause separation between loved ones, and those who endeavor to find faults in one who is innocent.’”
