Is it permissible to say that someone resembles the Prophet (blessings and peace of Allah be upon him)?
Question

                My question is: is it permissible for us to say of someone that he has some resemblance to the Messenger of Allah (blessings and peace of Allah be upon him), if that resemblance is in physical terms only, and not in character or anything else?
Praise be to Allah.
    There is 
    nothing wrong with the Muslim saying that So and so resembles the Prophet 
    (blessings and peace of Allah be upon him), whether that is physically or in 
    character, if that is indeed the case with regard to that person. 

    It was 
    narrated that al-Bara’ ibn ‘Aazib (may Allah be pleased with him) said: the 
    Prophet (blessings and peace of Allah be upon him) said to ‘Ali: “You are of 
    me and I am of you.” And he said to Ja‘far: “You resemble me physically and 
    in character.” And he said to Zayd: “You are our brother and our friend 
    (mawla).” 

    Narrated by 
    al-Bukhaari, 2700. 

    Similar things 
    were said by many of the Sahaabah. 

    It was 
    narrated that Anas ibn Maalik said: No one resembled the Prophet (blessings 
    and peace of Allah be upon him) more than al-Hasan ibn ‘Ali. 

    Narrated by 
    al-Bukhaari, 3752. 

    And he said 
    concerning al-Husayn ibn ‘Ali: He was the closest of them in resemblance to 
    the Messenger of Allah (blessings and peace of Allah be upon him). 
    

    Narrated by 
    al-Bukhaari, 3748.

    Al-Haafiz Ibn 
    Hajar said: 

    Those who 
    resembled the Prophet (blessings and peace of Allah be upon him), other than 
    al-Hasan and al-Husayn, were: Ja‘far ibn Abi Taalib and his son ‘Abdullah 
    ibn Ja‘far, Qutham ibn al-‘Abbaas ibn ‘Abd al-Muttalib, Abu Sufyaan ibn 
    al-Haarith ibn ‘Abd al-Muttalib and Muslim ibn ‘Aqeel ibn Abi Taalib.

    Among people 
    other than Banu Haashim were: as-Saa’ib ibn Yazeed al-Muttalibi, the 
    great-grandfather of Imam ash-Shaafa‘i, ‘Abdullah ibn ‘Aamir ibn Kareez 
    al-‘Abshami, and Kaabis ibn Rabee‘ah ibn ‘Adiyy. And these add up to ten.

    Ibn al-Jawzi 
    said: Among the Taabi‘een there was a man called Kaabis ibn Rabee‘ah 
    as-Saami… he resembled him (the Prophet (blessings and peace of Allah be 
    upon him)). Mu‘aawiyah sent for him and kissed him on his forehead, and he 
    allocated something to him. When Anas ibn Maalik saw him, he wept.

    Some of the 
    scholars mentioned people other than these; anyone who has full knowledge of 
    the attributes of the Prophet (blessings and peace of Allah be upon him) 
    will understand that. 

    Ibn ‘Abd 
    al-Haadi said of a man called ‘Abdullah ibn ‘Awaanah al-Maghribi, who was a 
    contemporary of his: More than one of the shaykhs who had knowledge of the 
    attributes of the Prophet (blessings and peace of Allah be upon him) told me 
    that this man, al-Maghribi, was similar in physical appearance to the 
    Prophet (blessings and peace of Allah be upon him).

    Likewise, 
    resemblance may be in character attitude. 

    Hudhayfah ibn 
    al-Yamaan said: The closest of the people in resemblance to the Messenger of 
    Allah (blessings and peace of Allah be upon him) in terms of conduct, 
    humility and dignity, was Ibn Umm ‘Abd. Narrated by al-Bukhaari, 6097. 

    Ibn Umm ‘Abd 
    is ‘Abdullah ibn Mas‘ood (may Allah be pleased with him). 

    It was 
    narrated that ‘Aa’ishah, the Mother of the Believers, said: I have never 
    seen anyone closer in resemblance to the Messenger of Allah (blessings and 
    peace of Allah be upon him) in terms of conduct, humility and dignity, or in 
    the manner of standing and sitting, than Faatimah bint Rasool-Allah 
    (blessings and peace of Allah be upon him). 

    Narrated by 
    at-Tirmidhi, 3762. He said: This is a hasan saheeh hadeeth. It was classed 
    as saheeh by al-Albaani. 

    The wordsconduct, humility and dignity are close in meaning; what they refer 
    to is good manners, meekness and calmness, and so on. See: ‘Awn 
    al-Ma‘bood, 14/87
