What is the ruling on taking a loan with interest from the municipality to pay for home insurance, knowing that its repayment can be postponed in case of inability to pay, and is this considered a Qard Hasan (a benevolent loan)?

If the loan is repaid with an increase stipulated in the contract, it is forbidden usury (riba), one of the gravest major sins, regardless of whether the increase is large or small. This is because any increase in a loan or benefit that the lender gains is forbidden usury if it is stipulated as a condition.

Similarly, a late payment fee for a loan is considered forbidden usury. It is a void condition that must not be fulfilled and is not permissible, as it is the very essence of the forbidden usury of the pre-Islamic era (Jahiliyyah).

You must repent to Allah Almighty and strive to avoid paying the usurious increase as much as you can.
