[Q]: I am a businessman and the day after thanksgiving is the busiest sale day of the year, known as 'Black Friday'. Is it permissible to have special deals and prices on my goods on this day? Or is this considered to be an imitation of the non Muslims?
[A]: Shaykh Ḥasan ibn 'AbdulWahhāb al-Bannā:
The reason why they probably call it 'Black Friday' is because in the talmūd which is the explanation of the Torah, written by the aḥbār, it is written that Friday has in it an hour which is considered a miserable, and an unlucky hour (bad fortune).
However, our Messenger (صلى الله عليه و سلم) mentioned regarding Friday, “There is an hour on Friday that if any Muslim makes du‘ā’ during it, his du‘ā’ will definitely be answered.”
We have two possibilities here;
The first possibility as a businessman is that you do your sale with a different intention so you will be competing with those (businesses) around you.
What I fear for you though, (as a businessman) is that if you were to write a sign and place it near your store stating that this so called 'Black Friday' is against the natural disposition of any human being, it may get you in trouble with your customers or neighbours. Therefore you (should) hold the sale with a different intention as to ensure you are not participating in black Friday.
However, what is better for you is that you close your store completely on that day to show the people or those who may later enquire that you are not confessing to the term 'Black Friday' and that this in itself is wrong. This is because it is a way of accusing Islām and the Messenger of Islām to call the day of Friday, a 'black Friday'.
If you close your shop on that day it would be best for you, and thereafter you can hold sales on any other day whether it is before the celebrations or after it; that will be better for you.
I (translator) mentioned to the Shaykh:
O Shaykh, will that resemble the actions of the Jews? When Allāh commanded them not to fish on Saturday and they threw their nets in the water on Friday and collected it on Sunday.
Shaykh Ḥasan ibn 'AbdulWahhāb al-Bannā:
No, Allāh commanded the Jews not to fish on Friday and that's why they played games and thus they opposed the command of Allāh. However, in our case Allāh commanded us to stand for our Religion and the Messenger of this Religion.
This issue of sales regarding merchandise, trade or business is not the same (here). Even in Egypt some of the stores that try to sell their summer inventories hold sales so they can begin to prepare for the next season (of winter sales).
And Allāh knows best.
