13 - Chapter on the forelock (al-dhu'ābah)

4193 - Aḥmad ibn Ḥanbal narrated to us, ʿUthmān ibn ʿUthmān narrated to us — Aḥmad said: he was a righteous man — ʿUmar ibn Nāfiʿ informed us, from his father, from Ibn ʿUmar, who said: The Messenger of Allah, peace and blessings be upon him, forbade al-qazaʿ. Al-qazaʿ is that a boy's head is shaved, leaving some of his hair.

============================================
It was also recorded by al-Nasā'ī in al-Kubrā (8104), (8550), and (9249) via the chain of Wahb ibn Jarīr, with this same chain of transmission.
It is in Musnad Aḥmad (1750).

(1) Al-dhu'ābah: the braided lock of hair from the head.
(2) A sound ḥadīth, and this chain is good on account of ʿUthmān ibn ʿUthmān — who is al-Ghaṭafānī al-Baṣrī — and he was followed in the two ḥadīths that come after it.
It was also recorded by al-Bukhārī (5920), Muslim (2120), Ibn Mājah (3637), and al-Nasā'ī in al-Kubrā (9253) and (9254) via the chain of ʿUbayd Allāh ibn ʿUmar al-ʿUmarī, and Muslim (2120) via the chain of Rawḥ ibn al-Qāsim, and (2120) via the chain of ʿUthmān ibn ʿUthmān al-Ghaṭafānī — all three of them from ʿUmar ibn Nāfiʿ, with it.
It was also recorded by al-Nasā'ī in al-Kubrā (9255–9257) via the chain of ʿUbayd Allāh ibn ʿUmar, from Nāfiʿ, from Ibn ʿUmar, without mentioning ʿUmar ibn Nāfiʿ, and al-Nasā'ī deemed correct the narration of ʿUbayd Allāh from ʿUmar ibn Nāfiʿ, from his father, even though ʿUbayd Allāh's hearing from Nāfiʿ is well-known and famous.
It was also recorded by Muslim (2120) via the chain of ʿAbd al-Raḥmān al-Sarrāj, from Nāfiʿ, with it.
It was also recorded by al-Bukhārī (5921) and Ibn Mājah (3638) via the chain of ʿAbd Allāh ibn Dīnār, from Ibn ʿUmar.
It is in Musnad Aḥmad (4473) and Ṣaḥīḥ Ibn Ḥibbān (5506).
See the two that follow it.

His saying: "about al-qazaʿ." Al-Sindī said: it is with two fatḥahs, the first letter being qāf and the second zāy with a dot: its origin is the cutting of clouds, and it is said for shaving a boy's head while leaving places on it, as a comparison to it.
