Travelling while in iddat

Q: I’m on iddah at present and have been keeping to the confinement of my home as per the rules of Islam. However, my daughter has been experiencing emotional and psychological distress to my divorce as we had to pack up and leave our home in a few days and start a fresh. She is seeing a therapist at present. 

My brother is going away for the weekend and suggested that I join him with my daughter going to the destination and staying in the room whilst he does activity with her. I unfortunately have to drive because he is taking his family with him and there is no space in the car. Is this allowed considering the circumstances. It’s been six weeks since my iddah and I don’t don’t want to break the rules.

Purchaser demanding a refund one month after purchase

Q: I advertised a hunting scope on an online platform. In the description I wrote the name and the condition of the scope been fair condition. An individual messaged and on 20 March 2024 and I sold the hunting scope to this individual. 

On 25 March he confirmed receiving the scope and was happy. A month later he messaged saying the scope is not working and demanding a refund. I said its one month later and I can't do anything as its a second hand item and was bought and sold as second hand goods. Then he demands a receipt for the item which could not be provided as its second hand goods with no warranty. 

Apparently he wanted the receipt as the company of this scope has a lifetime warranty which he could claim if he had an original receipt which could not be provided. The scope was sold for R2000 which was in fair condition. All pictures of the scope was shown to the individual before purchasing. A scope brand new is about 8 to R10000. Its been around 5 months since the purchase. What do I do in this situation?
