Is it permissible to use a personal credit card to purchase the needs of one's employer, and to pay the bank the cash amount received for that purpose, in order to benefit from the accumulated airline ticket points?

The question includes two matters:

1. The ruling on using a Visa card: There is no objection to it if it is free from Sharia prohibitions. 2. The ruling on the questioner purchasing for the company using the card instead of paying the price they advanced him: This is permissible, but the points and gifts resulting from the transaction belong to the company. Therefore, their permission must be sought. If they permit it, there is no objection. Otherwise, the points belong to the client because he is the real buyer.
