rent

Dear brothers:Living a west, should a person who rents a residential place be concerned about the possibility of an existing mortgage on the property ( which translates into Riba)? Is the renter obliged to  invistigate this such thing before renting?Baiscally, can one lives and prays in a place that is purchased vai mortgage?asalum -al-alukum 

Respected scholars, as-salamu `alaykum.There is a woman who is unable to carry a pregnancy to full term. What is the ruling on taking one of her eggs, fertilizing it with her husband’s sperm, then, implanting it in the womb of another woman, whether or not that is in return for payment? Jazakum Allahu khayran.

Assalam alaikum, my husband and I are looking to move to a bigger house as we are expecting.We found a house on second floor of a building and the owner runs a liquor and pharmacy store in the first floor.The house has a separate entrance.Is it permissible to stay on rent in this house?

my brother took a shop on rent.to get it he had to pay some money to the the person who was alreading renting it. is such a payment halaal.ie money is given to a person who doesnot own that shop so that my brother can now use it.now after some time my brother is planning to vacate it. and he will give the shop to another person only if he gotsome money for it, even though he doesnot own it. is this halaal i see that such practices are widespread.some are saying that it is haraamthe owner doesnot care about these transactions as long as he gets the rent which he has stipulated.the contract isbetween the rentee and the owner.

As-Salamu `Alaykum! We have property that is for rent in addition to the house we live in. How do we calculate Zakah on this property? Is it based on the market value of the property or on rental income, or both? We have had very opposing information. Please clarify this matter for us.
