Is it obligatory to dispose of items purchased with money from speculative profits, and what is the ruling on recovering capital while retaining the purchases?

If a person does not trade with the money or invest it, then he must return the capital to its owners. What was given as profit is counted from the capital, and what was consumed from it is not blameworthy. The worker is sinful in his deception, and he guarantees the capital if he neglects or transgresses.
