But, if he wants to faorgo the debt or right owed to him, the acceptance by the opposite person is not necessary.

If a debtor knows the amount he owes, but the creditor does not know and makes compromise with the debtor for an amount less than what is owed to him, like, if the creditor has to receive $50 but he unknowingly makes a compromise for $10, the balance of $40 is notHalal (allowed) for the debtor, except that he himself tells the creditor what he actually owes him, and seeks his agreement.

Alternatively, the debtor should be sure that even if the creditors had known the exact amount of the debt, he would have still settled for that lesser amount. As long as the buyer and the seller do not leave the place where a transaction was concluded, they can cancel the transaction. Also, if a buyer purchases an animal, he has the right to cancel the transaction within three days.

And similarly, if the buyer does not pay within three days, for the commodity purchased by him, and dose not take delivery of the commodity, the seller can cancel the transaction, as stated in rule no. However, one who makes a compromise in respect of some property, does not possess the right to cancel the compromise in these three cases.

However, if the other makes unusual delay in delivering the property over which the compromise was reached, or if it has been stipulated that the property will be delivered immediately, and the opposite party does not act according to this condition, the compromise can be cancelled.

And similarly, compromise can also be cancelled in other cases which have been mentioned in connection with the rules relating to purchase and sale, except in the case when one of the two parties in compromise has been defrauded, in which the compromise can not be cancelled if the compromise is for ending the quarrel; and even in other conditions, the defrauded person cannot, as an obligatory precaution cancell the compromise.

A compromise can be cancelled if the thing received by means of compromise is defective. However, it is a matter of Ishkal, if the person concerned desires to take the difference of the price between the defective thing and the one without defect. If a person makes a compromise with another person with his property and imposes the condition that after his death the other person will, for example, make that property Mawqufah, and that person also accepts this condition, he should carry it out.
