The Expiation for Blood in Ramadan and the Criterion for Inability

Question:
A questioner asks: What is the expiation for blood during the day in Ramadan if one is unable to free a slave or fast for two months, and what is the criterion for that?

Answer:
The man who came to the Prophet (peace and blessings be upon him) and informed him that he had intercourse with his wife at the end of Ramadan. He said to him (peace and blessings be upon him): Do you find a slave to free? He said: No. He said: Do you fast for two consecutive months?
He said: I am unable. He said: I have been afflicted by the tents. He said to him: Feed a poor person. He said: No, more than that. So he sat with the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) left him. Then a basket containing dates was brought to the Prophet (peace and blessings be upon him), and he said to him: Eat this and give it in charity. He said: There are poorer people than us, and by Allah, there is no household between the two hills poorer than him. He said (peace and blessings be upon him): Take it and spend it on your family.
Some of the scholars say that this means the expiation was dropped from him due to his separation, and some of the scholars say that the expiation was not dropped, but it remains in his liability, so if he is able, he will benefit from it.
According to the Hanbalis, if he marries, he said: Like the provision, if he does not find it, it is dropped. So they cited this as much evidence.
