The appliances that the owners bring to you to fix are regarded as a trust that is left with you, and you must keep them and look after them until their owners come to collect them. However, if the owner of the appliance is later than usual in coming to collect his appliance after you have fixed it, and you have lost hope that he will return, or his leaving the appliance is detrimental to your business because you do not have much room, or because it is difficult to keep them and alike, in this case you have the right to sell these appliances at the market price, and take from that your fee as agreed upon with the customer, and set the rest of that money aside. Then if the owner comes along some day, you can give the remaining money back to him.

If the company stipulated the price to an agent and agreed with him that if he sells it for more the extra money would be his, it is permissible for the agent to sell it for more and he can take the extra money.

It is not permissible for a partner or proxy to buy something from himself, except with the permission of his partner or the one who appointed him as his proxy. If your partners give you permission to do that, and they are adults of sound mind, then there is nothing wrong with it in that case.

If your work involves helping the company in any way with any kind of cheating or stealing, then it is not permissible. But if your work has nothing to do with the haram things, and the company also has some other departments that do not deal with haram things, then it is permissible for you to work in the departments that deal with permissible things.

Islamic banks are based on permissible transactions such as selling, buying, profit sharing, partnerships and other Islamically-acceptable forms of investment. The interest-based system on which commercial banks are based is a prohibited system that is based on lending and borrowing with Riba.

If the bank adheres to investing the deposits in permissible projects without guaranteeing the customer’s capital, and agreeing with the customer on a defined share of the profits, then there is nothing wrong with making investment deposits in this bank, and there is also nothing wrong with opening a current account with it.

It is not permissible for the lender to stipulate in a loan contract that the borrower must pay back the loan with more than he took. It is permissible to make the borrower pay the costs of issuing the loan and other related services, on condition that the amount paid is equal to the real costs involved in issuing the loan.

Alternatives for Islamic Banks to avoid late-payment charges include: 1- the bank appointing someone as a guarantor; 2- the bank taking something in mortgage; 3- the bank stipulating that the customer should open an account in the bank; and 4- the bank putting the customer on a blacklist.

If the bank buys the house then sells it to you in installments, there is nothing wrong with that, but if it does not buy it, rather it is giving you the money or paying it on your behalf, on the basis that it will get the money back plus an additional amount, then this is riba.
