He was also asked:
A man owns a slave whom an oppressive man wishes to buy. Fearing that the prospective buyer would not pay him, he said, “Whenever I sell this slave, his price is forbidden to me.” The owner owes a debt. May he sell the slave and use the proceeds to repay it?
He replied:
Yes, he may sell him and pay people what he owes them.
If, by saying, “His price is forbidden to me,” he meant that he would not retain the proceeds but would instead pay his creditors, nothing is required of him. If, however, he intended to declare the proceeds forbidden to himself, one view is that he must offer expiation for an oath, as held by Ahmad and Abū Hanīfa. Another view is that nothing is required of him, as held by Mālik and al-Shāfi‘ī. And Allah knows best.
He was also asked:
A man owes debts and owns property in al-Qarāfa. He sold half of it under a repurchase arrangement and has testimony establishing this. The purchaser publicized it every month, through his efforts and a half, from the date of the sale. Another creditor lodged a complaint against him and used force to pressure him until he took the remainder of the proceeds of the first sale, while the property remained in the second creditor’s possession. What is the ruling?
