Is it permissible for men to wear jeans (tight clothes)? Do they harm prayers?

I hear from the people around that wearing jeans is contrary to the Sunnah? Is it true?

Dear Brother / Sister,

In Islam, not all items of clothing are mentioned one by one; decrees were not made for each garment separately? Since there were, are and will be thousands of kinds of items of clothing, it is not possible. However, there are general rules about clothes in Islam as it is the case for everything. Islamic scholars evaluate the items of clothing that appear based on those rules.   

Accordingly, for a man, it is fard to wear clothes that are enough to cover his body parts that are necessary to be covered and that will protect him from heat and cold. It is mustahab to wear more things than the obligatory amount to beautify his appearance as a Muslim and complete his clothing like izar (something worn around legs), rida (something worn around the upper part of the body) gown, shirt and turban.  For, Allah likes to see the signs of His boons on His servant. (Fetavay-ı Ankaravî, I/167).

The Messenger of Allah (pbuh) stated the following:

"Make your clothes beautiful; keep your things neat and be like white mounds among people."(Suyuti, aI-Jamius-Saghir, I/192)

It is permissible to wear clean and new clothes especially on Friday and eid days in a way that will not disturb the needy. It is makruh to wear red clothes all over, and according to some scholars, also yellow clothes. It is haram to wear clothes for conceitedness and show off and in order to appear beautiful to women, to wear the clothes that resemble those of non-Muslims and clothes woven from pure silk.

The clothes that are so transparent as to show the color of the parts that need to be covered are regarded as non-existent (haram).

It is makruh to wear thick but tight clothes that make the form of parts of the body that need to be covered distinct. The decree about the organs that do not have to be covered like the head and arm is based on the customs of the Muslims of that area. It is makruh to open them in places where it is deemed abnormal by Muslims and permissible to open them in places where it is not deemed abnormal. (Shatibi, al-Muwafaqat).

Accordingly, it is permissible to wear jeans but

1. if they are so tight as to stick the body,

2. and if they are generally disliked by Muslims, it cannot be said that they are not makruh, that is, they are fully permissible. (Allah knows the best.)

If these two drawbacks disappear, that is, if they are not too tight and if they are not condemned in the community where one lives, it is permissible to wear them.

Prayers performed by wearing jeans are valid even if they are tight.
