الحسن بن خنيس الكوفي

I said to Abu Abdillah (as), "Abdur-Rahman ibn Sayabah has a debt owed to him by a man who has died. We spoke to him about forgiving it, but he refused." Imam (as) said: "Woe to him! Does he not know that for every dirham he forgives, he will receive ten in return? But if he does not forgive, then he will only receive a dirham in exchange for a dirham."

“Once I said to abu ‘Abd Allah (a.s.), ‘A man who died had borrowed (money) from ‘Abd al-Rahman ibn Sayabah, whom we asked to waive the loan in favor of the dead person, but he refused. He (the Imam) said, “Woe is upon him! Why does he not realize that for every dirham, he can receive the reward for ten dirhams, were he to waive it in favor of the dead person? In not waiving the loan in favor of the dead person, he can only receive the reward of one dirham for every dirham.’””
