It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed Allah Almighty dislikes a seventy-year-old who adopts the appearance of a twenty-year-old youth in his gait and outward look."
Imam al-Tabarani (may Allah have mercy on him) said: "This hadith is not narrated from the Messenger of Allah (peace and blessings be upon him) except with this chain, and Musa bin Muhammad bin Ibrahim is alone in narrating it."
