Surety 2item I lent someone a sum of money, which he did not pay back. A relative of his wrote me a post-dated check for the amount of the debt provided that I allow him some time [to settle the debt]. Thus, he undertook to pay me back the debt if the original debtor defaulted. The debtor ran away without leaving a trace, so much so that I lost every contact with him. Is it shar‘ī that I get back the whole amount of debt from the surety? Is it permissible for a person, who has no funds in the bank, to write a check with a view to standing surety for someone else?
