Abu Karimah says: I heard Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) say, while delivering a sermon in Kufah: O people! I heard the Prophet (peace and blessings be upon him) say: "Beware of wearing the dress of monks! For whoever adopts monasticism (the narrator is unsure; perhaps the words are:) or imitates them, has nothing to do with me."
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat from his teacher Ali bin Sa'id al-Razi, and he is da'if (weak).

Hadith Takhrij«أخرجه المعجم الأوسط للطبراني برقم: 3921»
It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that he said: The Prophet (peace and blessings be upon him) came out to some elders of the Ansar whose beards were white, and he said: "O assembly of the Ansar! Dye (the hair of your beards) red or yellow, and differ from the People of the Book." The narrator says: We said: "O Messenger of Allah, the People of the Book wear trousers and do not wear the lower wrap (izar)?" The Prophet (peace and blessings be upon him) said: "Wear trousers and also wear the lower wrap, and differ from the People of the Book!" We said: "O Messenger of Allah, the People of the Book wear leather socks (khuffs) and do not wear sandals." The Prophet (peace and blessings be upon him) said: "Wear leather socks and also wear sandals, and differ from the People of the Book!" We said: "O Messenger of Allah, the People of the Book trim their beards and let their moustaches grow long." Then the Prophet (peace and blessings be upon him) said: "Trim your moustaches and let your beards grow, and differ from the People of the Book."
Imam Ahmad and Imam al-Tabarani recorded it. The narrators of Imam Ahmad are the narrators of the Sahih, except al-Qasim, and he is thiqah (trustworthy); some criticism has been made of him that is not harmful.

It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) that he said: The people said: "O Messenger of Allah, the polytheists wear trousers (or pyjamas) and do not wear the lower wrap (izar)." The Prophet (peace and blessings be upon him) said: "You should wear trousers and also tie the lower wrap!" They said: "O Messenger of Allah, the polytheists go barefoot and do not wear sandals."
