Sahih Muslim, 6083

Rapporté par Jabir ibn Samura رضي الله عنه : « On a demandé à Jabir ibn Samura رضي الله عنه à propos de la vieillesse du Messager d’Allah ﷺ. Il a dit : “Quand il mettait de l’huile sur ses cheveux, on ne voyait rien (qui montre la vieillesse), mais quand il n’en mettait pas, on voyait quelque chose.” »

Jabir b. Samura was asked about the old age of Allah's Apostle (ﷺ). He said:When he oiled his head nothing was seen (as a mark of old age) and when he did not apply oil something (of the old age) became visible
