Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Indeed, Allah Almighty dislikes a seventy-year-old who adopts the appearance of a twenty-year-old in his walk and his look."
Imam al-Tabarani recorded this narration in al-Mu'jam al-Awsat, and he said: It is narrated from the Prophet (peace and blessings be upon him) only with this chain. Its chain contains a narrator, Musa bin Muhammad bin Ibrahim bin al-Harith, who is da'if (weak).
