Is it Sunnah to wear green clothes?
Question

                Ive seen few Islamic sects, always wearing green turban and white clothes, or all green clothes, stating it as to be following Sunnah of Prophet Sallalahualayhi wassalm. What is the context behind it?.
Praise be to Allah.
    Firstly: 

    The basic principle with regard to clothing is that it is 
    permissible and the Muslim may wear whatever colour of clothing he likes, 
    except that which was forbidden by the Prophet (blessings and peace of Allah 
    be upon him), which is red and yellow. The best colour that a man may wear 
    is white, because of the hadeeth narrated by Ibn ‘Abbaas (may Allah be 
    pleased with him) who said: The Messenger of Allah (blessings and peace of 
    Allah be upon him) said: “Wear white garments, for they are among the best 
    of your garments, and shroud your dead in them.”

    Narrated by Abu Dawood, 3380; at-Tirmidhi, 915

    It says in Fataawa al-Lajnah ad-Daa’imah, 24/18: It is 
    proven that the Prophet (blessings and peace of Allah be upon him) preferred 
    white clothing over other colours. With regard to other colours, there is no 
    proof that any of them are preferred. What is prescribed for the Muslim is 
    to wear that which will cover him and not to go to great expense in doing 
    that. This is the teaching of the Prophet (blessings and peace of Allah be 
    upon him). One should also avoid wearing clothes of fame and vanity, and 
    anything that resembles the clothing of women or disbelievers, or anything 
    that is contrary to Islamic teachings. End quote.

    ‘Abdullah ibn Ghadyaan; Shaykh Saalih al-Fawzaan; Shaykh Bakr Abu Zayd 

    Based on that, wearing green clothes is permissible but it is 
    not Sunnah and there is no virtue in wearing them. 

    If wearing green clothes is a symbol for some of those who 
    follow innovation, such as Sufi tariqas, then it is better for the Muslim 
    not to resemble them. 

    And Allah knows best.
