1651 — Isa ibn Ali informed us; Abdullah ibn Muhammad al-Baghawi informed us. He said: Abdullah ibn Awf al-Kharraz informed us. He said: Hushaym informed us; Mansur informed us, from al-Hasan, from Abu Bakrah, who said: The Messenger of Allah, peace and blessings be upon him, said: “Modesty is part of faith, and faith leads to Paradise. Obscene speech is part of coarseness, and coarseness leads to the Fire.”

There is also a report from Abu Hurayrah with the same wording.
