A spokesperson said the company made the decision to stop selling fireworks in its 2,300 UK stores following a yearly review of all its products.
The spokesperson has declined to discuss why Sainsbury's has come to the decision, telling the media outlets that it is 'commercially sensitive'.
Multiple people have taken to social media to express their delight at the situation, outlining how fireworks can have negative impacts on many.
One Twitter user said: "Thank you so much for putting safety before profit and choosing not to sell fireworks this year. Animals, elderly, and vulnerable people suffer needlessly around this time of year, so to hear about this was fantastic. I can only hope other supermarkets etc follow suit."
Another added: "This is the best news ever. Every owner of an anxious dog or pet will be so thankful for this, and I hope other supermarkets follow. Thank you from all the animals."
Tesco and Asda will reportedly continue to sell fireworks.
