If a man swears that he will repay his debt “soon,” the word “soon” means less than one month; if he says “after a long time,” it means more than one month.
Whoever swears not to live in this house, then leaves it himself while allowing his family and possessions to remain inside, is perjured.
Whoever swears that he will ascend to the sky or turn this stone into gold, his oath is valid and he is deemed perjured the moment he fails to do so.
If someone swears that he will settle so-and-so’s debt today, pays it, and the creditor later discovers that some of the coins are slightly counterfeit, debased, or improperly struck, the oath is not broken. But if they prove to be mere lead or pewter pieces, he is perjured.
If a person swears that he will not collect his debt a dirham at a time, taking part of it does not break the oath—unless he eventually receives the whole amount in scattered instalments. Should he receive the payment in two weighings with no interruption other than the weighing itself, he is not perjured, for that is not considered dispersal.
Whoever swears that he will certainly travel to Basra and does not reach it before dying is perjured at the final moment of his life.
