What is the ruling on naming something "Black Friday," is it permissible in Islamic law, is it considered imitation of the disbelievers, is it forbidden as a means of averting evil, and are buying and selling during it unlawful?

Black Friday is known as a day of major discounts at the end of November. The origin of its name dates back to a financial crisis in 1869, then to police descriptions of traffic jams, and it is also said to refer to the use of black ink to record profits. It is permissible to buy and benefit from the offers on this day for permissible items, but it is not permissible for shop owners to dedicate this day to discounts in imitation of the disbelievers.
