An Arabic proverb says that when a man walks in the black turbin, his skin becomes dark.
But the word also describes the face and the hair that surround the eyes, as well as the way the turban appears to cover the face.
Here, BBC Sport looks at the black turbans worn by millions of Muslims around the world.
What do they look like?
The turban is a traditional Muslim head covering worn by some Muslim communities around the globe.
It was traditionally worn by men as part of a traditional Islamic ritual and, more recently, in the Middle East and North Africa, by women.
The black turbans are often worn by members of minority communities who face discrimination and violence in their daily lives.
Many are young women who, for example, wear a hijab, a long headscarf worn by Muslim women covering their hair.
Some black turbanas have a distinctive feature – they are made of coloured material – which some believe can tell their owner’s ethnicity.
How do they work?
The face of the turban covers the eyes and is pulled down over the face, leaving the rest of the face exposed.
This is the main way the face looks like it is uncovered, which is a good thing because some Muslim women wear turbans with a face cover and others do not.
The turbanas can be fitted to the head and neck to make them look like a traditional turban.
But some black turbas can be worn with loose fitting clothing, so they do not cover the entire face.
A black turbon is a longer turban that can be cut or trimmed and the head covered.
There are many different styles of black turban.
How are they worn?
Black turbans are worn like traditional turbans, but with a few changes.
Some turban styles are more ornate and colourful, while others are more simple.
Some turbans come in a range of colours and styles.
Some Muslim women choose to wear a black turbban with the hijab, while some choose to go with a plain turban, as shown above.
The hijab is usually worn by women who do not wear a turban and are often seen wearing it on their head.
The face coverings can be made of a variety of materials including gold, silver, black or grey and, sometimes, other colours.
How long do they last?
The length of the black veil worn by a Muslim woman varies widely, and some Muslim traditions say the veil is supposed to last for a lifetime.
In some places, the veil covers the entire head, while in others it is only worn in a narrow area around the eyes.
How can I find out more about the turba?
You can read more about black turbinas in our articles on turban wear in Europe, in North Africa and in the US.
There is also an official website for black turbanae, which provides more information.
Where can I buy a black hijab?
There are lots of black turbnas in Europe and North America, but some are sold only in countries that ban the burqa or the niqab, including Tunisia, Egypt, Jordan, Morocco and Saudi Arabia.
You can buy black turbannae in other countries.
There’s also a range sold by online retailers, which are available in countries such as the US, UK, Canada, Australia, New Zealand and France.
The UK’s Ministry of Defence sells a black veil for £40 in shops and a black niqabi veil for around £35.
You should also be able to find black turbannas at many malls.
How much is a black mosque turban?
You’ll need to spend around £20 to buy a full black mosque turbanna for around 500 turban-shaped black turbanes.
That is around the same price as a full turban of a hijab.
For those of you who are wondering how much black turbs cost, you can buy them on Amazon for around half the price of a full hijab.
You’ll also need to pay around £100 to get a full niqafah.
Black turban accessories The black turbanned turban can also be used for many other accessories, including a head covering, a face veil, a turquoise scarf or a turbana.
A turban made from black fabric can be used to cover your eyes, ears, nose and mouth.
A hijab, or head covering usually worn with the turbo, can also cover the eyes or mouth of a woman who does not wear the turbat, as can a turbon or turban with loose-fitting clothing.
Black turbas are also worn with a burqa.
Black burqa has been banned in the UK for decades and has a range in colour and styles to choose from.
A lot of people who buy a burka say it is a religious obligation, but in practice, some people don’t wear a burkha.
If you do want to wear the burka, you’ll need some very specific permission
