Green Clothing in Islam:
The wearing of green clothing was greatly liked by Rasulullah (saws) to such an extent that Anas says, “Green was the colour most liked by Rasulullah.” (Narrated by Tabarani in Al-Awsat)
A number of narrations regarding Nabi wearing green are mentioned in Subulul Huda war Rashad (vol 7 pg 312)
‘Allama ibn Battal, Ibn Hajar and Munawi have all mentioned that the clothing of the inhabitants of Jannah will be green. This can be deduced from the Ayah, “The inhabitants of Paradise will wear green clothing.” (Surah Kahf, v.31)
‘Allama Tabari narrated that the Khalifa al Ma’mun and his entire army wore green attire; to such an extent that even their caps were green.” Tarikh al Tabari
(This part was taken from Mufti Husain Kadodia's, 'Crown of a Believer')
Green color worn by women in the time of Nabi(saws):
Imam Bukhari narrated in his Sahih: Narrated Umm Khalid bint Khalid:
The Prophet (saws) was given some clothes including a black Khamisa. The Prophet (saws) said, "To whom shall we give this to wear?" The people kept silent whereupon the Prophet (saws) said, "Fetch Umm Khalid for me." I was brought carried (as I was small girl at that time). The Prophet took the Khamisa in his hands and made me wear it and said, "May you live so long that your dress will wear out and you will mend it many times." On the Khamisa there were some green or pale designs (The Prophet saw these designs) and said, "O Umm Khalid! This is beautiful." 7:72:713.
He also narrated: Narrated 'Ikrima:
"Rifa'a divorced his wife whereupon 'Abdur Rahman bin Az-Zubair Al-Qurazi married her. 'Aisha said that the lady (came), wearing a green veil (and complained to her (Aisha) of her husband …..till the end." 7:72:715.
The Prophet’s wearing green:
When Allah's Apostle died, he was covered with a Hibra Burd (green square decorated garment). (Sahih al Bukhari)
From Abu Rimtha ‘I went with my father to Rasulullah (saws) and I saw that he had on him two green cloaks”. (Abu Dawood)
