What is the ruling on buying a house in one's home country with a loan, knowing that the questioner lives abroad in rented accommodation?

If the loan is a Qard Hasan (a benevolent loan with no interest), there is no harm in taking it to buy a house. However, if it is an interest-based (riba-based) loan, it is not permissible to proceed with it to buy a house or anything else, except in cases of dire necessity. Islamic banks offer legitimate alternatives, such as Murabaha (cost-plus financing) or Istisna' (manufacturing contract), which obviate the need to resort to prohibited transactions.
