I offered a water well for sale without specifying a price. An intermediary informed me that a company wished to purchase it, including all procedures, for 350,000 dinars.

What is the Islamic ruling regarding this sum of 100,000 dinars? Does it rightfully belong to the seller, or should it be returned to the buyer?

My maternal uncle bought an apartment through an Islamic bank and wanted to sell it to me before he completed the installments. He had paid the bank 5,000 dinars and said to me: 'Buy the apartment from me in return for 7,000 dinars (5,000 paid as down payment and 2,000 as profit ), and you continue paying the bank installments. Once they are completed, the transfer of ownership will occur.' I paid him 7,000 dinars and continued to pay the apartment installments through the same bank via his account until now. However, my uncle passed away and the bank absolved him from the remaining installments. Am I absolved from these installments as well?

I contacted the manufacturing company, and they said, "There is no exclusive distributor for the book, and you can buy and sell it as you wish." Is it permissible for me to sell the book?
