11.Al-Ḥusayn ibn ʿUlwān narrated from ʿAmr ibn Khālid, from Zayd ibn ʿAlī, from his fathers, from ʿAlī who said,

“I heard the Messenger of Allah (ṣ) say, ‘Speech is of three types: the profitable, the sound, and the detrimental. As for the profitable [speech], it is that where Allah is mentioned. As for the sound [speech], it is that wherein what Allah likes is spoken. And as for the detrimental [speech], it is that in which people are spoken about [in a negative way].’”
