Car dealership helping the customer acquire a credit facility with interest
Q: Is it permissible to own a car dealership whereby you sell cars to customers borrowing money from the bank and are paying interest?
From my understanding, even to witness the transaction is a sin. In this case we may be encouraging it to make a sale and helping the customer get finance. Is the profit from the sale halaal?
In some instances the banks give the dealers a kickback for arranging the finance with them, would this money be halaal?
