Green color in primary texts [Qur'an and Sunnah] 

The color green is a symbol of prosperity and good life. It is mentioned in the noble Qur`an as the color of garments and cushions of the people of Jannah [paradise]. 

Allah Almighty says,

Upon them will be green garments of fine silk and heavy brocade. [Al-Insan: 21] 

And they will wear green garments of fine silk and heavy brocade. [Al-Kahf: 31]

Reclining on green cushions [Al-Rahman: 76]

The Prophet (peace and blessings be upon him and his family) said that Allah will dress him in a green garment on the Day of Judgment as per his words: "When people are resurrected on the Day of Judgment, my community [ummah] and I will stand on top of a hill. Allah Most Exalted will dress me in a green garment and permit me to supplicate Him with whatever I wish. This is the praiseworthy position [al-Maqam al-Mahmoud]" [Recorded by Imam Ahmed).

The Prophet (peace and blessings be upon him and his family) also said that the souls of martyrs are kept in the crops of green birds. 

The dome of the Prophet's mosque is green 

In 1253 A.H. the dome of the Prophet's mosque was painted green.

Green color in modern studies

Modern scientific experiments proved that color green has a positive effect on man's psychological state. Therefore, it has good effects and there is no harm in being attached to it for these good reasons.

The ruling

The sound opinion, in this case, is to let people behave according to their natural disposition in regards to expressing their love for the Messenger (peace and blessings be upon him and his family) and by way of attaching themselves to the color of the garments of the people of paradise and believing in the unseen.
