Are the aforementioned circumstances considered a necessity that permits signing the second usurious loan?

Firstly: Borrowing with usury is forbidden and considered one of the major sins. The father must repent sincerely, regret his action, and resolve never to return to it.

Secondly: The father should seek a permissible means to obtain money, such as dealing through Murabaha (cost-plus financing) or Salam (forward sale). If he cannot find a permissible means and his failure to do so would result in his imprisonment and the loss of his land, then this constitutes a necessity that permits usury.

If the father is unable to borrow himself, it is permissible for you to borrow with usury to save him from imprisonment or the loss of his land due to necessity, provided that you detest usury in your heart.
