What is the evidence that he should put it in the interest of the Muslims as long as he is not the owner of this money in the Shariah, how is it allowed for him to dispose of it?

The second question: I work in the field of selling vegetables as a peddler. I buy from the market that is about forty kilometers away from me. Sometimes I find a blemish in the commodity ... It is customary that if the owner of the discount shop or the so-called "retailer" is asked to return an item because of the blemish, he will reduce the price of that commodity. If I returned the item on the same day, the transport costs would probably cost me more than the price. Is this indemnity i.e. the difference in the prices of the not defected and defected commodities, discount that we are asking forbidden to take?

O our Sheikh, there is a disagreement; to whom the Zakat should be paid? Is it to the government while it is known that it does not spend it in its allocated expenditures, or is it distributed to the poor (Al-Fuqaraa) and the paupers (Al-Masakeen)? Please clarify with evidences. Jazak Allah Khair.
