سنن أبي داود

Narrated Al-Bara' :

I did not see any man with locks hanging down to shoulders in red robe more beautiful than the Messenger of Allah (ﷺ). Muhammad b. Sulaiman added: He had hair which touched his shoulders.

Abu Dawud said: Isra'il also transmitted it in a similar way from Abu Ishaq saying: "(his hair) touched his shoulders". Shu'bah added: (His hair) reached the lobes of his ears.
