Sayyiduna Abbas (may Allah be pleased with him) narrated that a man came to the Messenger of Allah (peace and blessings be upon him) and said, "O Messenger of Allah, my mother has passed away and she still owed a month of fasting. Can I fast on her behalf to make up for it?" The Prophet replied, "Yes, Allah's debt is more deserving to be fulfilled."
