Assalamualaykum,
I have a question around cashback on phone contracts.
There are websites that offer cashback when you purchase a phone contract through them. (For example fonehouse.co.uk.)
At certain months during the contract, you have to go on the website, send your bill and you receive the cashback. The cashback is a fixed amount, for example £100 cashback to be claimed during a 12 month contract. The cashback is claimed during specific months, upto £100. There is a 60 day window for you to claim the cashback.
Was wondering if this is permissible?
