It is narrated from Safwan al-Jammal, who said: I said to Abu Abdullah عليه السلام: "I appointed a specific loan (aynah) for a man, and it became due. I said to him, 'Repay me.' He said: 'I do not have it now, so specify another loan for me until I can repay you.'" Imam عليه السلام said: "Specify it for him until he repays you."
