Is it obligatory for one who owes an expiation to accept money from another?

The questioner : If a person owes an expiation and has no money to give in charity, and another person gives him money to give in charity, is it obligatory for him to accept this money? And does he sin if he returns it?

The Shaykh : Because that without which an obligatory duty is not completed is itself obligatory. The answer is that he is not required to accept it; it is not obligatory. This is not a case of that without which an obligatory duty is not completed; rather, it is a case of that without which the obligation itself is not completed. And that without which the obligation is not completed is not obligatory, whereas that without which the obligatory duty is not completed is obligatory. The difference between the two is clear, is it not? That without which the obligation is not completed is not obligatory, and that without which the obligatory duty is not completed is obligatory. The difference between them is clear, O Sa'd. The difference is not clear? How do you say it? Is it clear to you? Good. For example, zakah is obligatory on one who possesses the minimum threshold. So, is it obligatory for me to strive in buying and selling to obtain the minimum threshold that makes zakah obligatory?
No. Good. A person has the minimum threshold, and the poor person is not near him; he needs the fare for a taxi. Is it obligatory for him to hire a taxi to deliver it to the poor person? Why? Because the obligatory duty is not completed without it, meaning the performance of the zakah is not completed without this. This is now another issue, as the brother mentioned: A person owes an expiation. Is he required to accept a gift from a person to expiate with the money? No, because it is not obligatory on him. Good. However, it is better not to accept it except from a person who has no favor over him and who is pleased when you accept from him. This is another matter.
