Imam Abu Bakr, may Allah have mercy on him, says that in the narration of Sayyiduna Abu Hurairah, may Allah be pleased with him, through Humaid from Imam Zuhri, it is mentioned: "Then you should fast for two consecutive months."

Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that a woman came to the Prophet (peace and blessings be upon him) and said that her sister had passed away and she owed two consecutive months of fasting. The Prophet (peace and blessings be upon him) said: "If your sister had a (monetary) debt, would you pay it off for her?" She replied, "Yes." The Prophet (peace and blessings be upon him) said: "Then Allah's right is more deserving to be fulfilled."
