Selling an item to someone not knowing whether they will use it for something impermissible

Q: 

1. Would it be halal for me to sell gold to a cash for gold place because there is a high chance they will sell this gold to a refiner, scrap gold buyer or so on and they might use this gold to make gold jewellery for men etc.? 

2. What about selling grapes to a business that sell grape related products so the grapes I sell to them can be used to make their grape juice or it can be used for their wine etc. Will the income be haram? Because I’m unsure what they will use it for.

Playing the Quraan in the home with the intention of protection and bringing barakah in the home

Q: My question is with regards to the Qur'aan cube/speaker. Is it permissible to keep the Quraan playing in the home while cooking, doing mundane daily tasks and leaving the Quraan playing while being in another room? Is this disrespectful to the Quraan Shareef or can it be done with the intention of protection and bringing barakah in the home?
