Abu Zayd ibn Akhtab (may Allah be pleased with him) reported: The Messenger of Allah (may Allah’s peace and blessings be upon him) wiped my face with his hand and supplicated for me. ‘Azrah (one of the narrators) said: "He lived for one hundred and twenty years and only had a few little grey hairs on his head.”

Explanation

The Messenger of Allah (may Allah’s peace and blessings be upon him) wiped over the face of Abu Zayd ibn Akhtab al-Ansāri (may Allah be pleased with him) with his hand and supplicated for him. According to another narration, the supplication made by the Prophet (may Allah's peace and blessings be upon him) was: "O Allah, make him beautiful, and make his beauty lasting", meaning: O Allah, make his beauty last throughout his life. ‘Azrah, one of the narrators, said that Abu Zayd al-Ansāri lived for one hundred and twenty years, and only a few little grey hairs were visible on his head till his death. In another narration, it was reported that Abu Zayd’s facial skin was smooth and wrinkle-free until the last day of his life, thanks to the Prophet's blessed supplication and his wipe over Abu Zayd's face.
