Abdullah bin Abbas (may Allah be pleased with them) narrates: A woman came to the service of the Prophet (peace be upon him) and said: O Messenger of Allah (peace be upon him)! My sister has passed away. She was obliged to fast for two consecutive months. The Prophet (peace be upon him) said: What do you think, if your sister had a debt, would you pay it off? She replied: Yes. The Prophet (peace be upon him) said: The right of Allah is more deserving to be fulfilled.
