"authentic according to the criteria of al-Bukhārī and Muslim if Sālim ibn Abī al-Jaʿd heard from ʿAbd Allāh ibn Masʿūd." al-Dhahabī agreed with this. I said: al-Bukhārī did not include ʿAmmār, and the isnād is disconnected. ʿAlī ibn al-Madīnī said: "Sālim ibn Abī al-Jaʿd did not meet Ibn Masʿūd." However, the ḥadīth is authentic, supported by what precedes it.

- "Change the gray hair and do not resemble the Jews and Christians." It was narrated by Aḥmad (2/261, 499) and Ibn Saʿd (1/439) from Muḥammad ibn ʿAmr from Abū Salamah from Abū Hurayrah as a marfūʿ ḥadīth. I said: Its isnād is good. ʿUmar ibn Abī Salamah also narrated it from his father with the same wording, except without mentioning the Christians. It was extracted by al-Tirmidhī (1/325) who said: "A good, authentic ḥadīth, and it has been narrated through other chains from Abū Hurayrah." Then it was narrated by him and al-Nasāʾī (2/278) and Aḥmad (1/165) and Ibn ʿAsākir (11/68/2) from Muḥammad ibn Kunāsah al-Asadī, who reported from Hishām ibn ʿUrwah from ʿUthmān ibn ʿUrwah from his father from al-Zubayr as a marfūʿ ḥadīth, without the phrase: "and the Christians." I said: This isnād's narrators are trustworthy, the narrators of al-Bukhārī and Muslim, except for Ibn Kunāsah, who is reliable
