3381—“Indeed, modesty, chastity, reticence of the tongue—not dullness of the heart—and religious understanding (1) are part of faith. They increase one’s share in the Hereafter and diminish one’s share in this world; yet what they increase in the Hereafter is greater than what they diminish in this world.

“Indeed, miserliness, obscenity, and vulgarity are part of hypocrisy. They diminish one’s share in the Hereafter and increase one’s share in this world; yet what they diminish in the Hereafter is greater than what they increase in this world.”

Yaʿqūb ibn Sufyān al-Fasawī recorded it in al-Maʿrifah. He said (1/311): Muḥammad ibn Abī al-Sarrī narrated to us: Bakr ibn Bishr al-ʿAsqalānī narrated to me: ʿAbd al-Ḥamīd ibn Suwwār narrated to me: Iyās ibn Muʿāwiyah ibn Qurrah al-Muzanī narrated to me, from his father, from his grandfather Qurrah al-Muzanī, who said:

“We were with the Messenger of Allah, peace and blessings be upon him, when modesty was mentioned in his presence. They said, ‘O Messenger of Allah, is modesty part of religion?’ The Messenger of Allah, peace and blessings be upon him, then related it.”

Through Yaʿqūb’s chain, al-Bayhaqī recorded it in al-Ādāb (132/199), al-Shuʿab (6/134–135), and Ibn ʿAsākir (10/6–7).

Al-Bayhaqī also recorded it in al-Shuʿab and al-Sunan al-Kubrā (10/194–195), as did al-Bukhārī in al-Tārīkh (4/1/181), Ibn Abī al-Dunyā in Makārim al-Akhlāq (19/87), al-Ṭabarānī in al-Muʿjam al-Kabīr (19/29–30), Khalaf-Wakīʿ in al-Quḍāh (1/318–319), and Abū Nuʿaym in al-Ḥilyah (3/125), all of them through
