You could get a gift card just to make him feel better.

Someone who works for me had his father pass away suddenly this weekend in Saudi Arabia. He will be away for the week but returning on the weekend. I want to send something from my team to express our condolences but heard flowers may not be appropriate as he is Muslim. I want to ensure I respect his culture and still ensure he knows we are thinking of him. What might be a good way to do this?
