There is another difficulty: Muslim narrated in his Sahīh (1), from ‘Abdullāh ibn ‘Abbās, that when the Messenger of Allah (peace and blessings be upon him) was told, “This day is held in honour by the Jews and Christians,” he said: “If (2) I live until next year, I shall certainly fast the ninth day.” But the Messenger of Allah (peace and blessings be upon him) died before the following year came. Muslim then narrated in his Sahīh (3), from al-Hakam [ibn] (4) al-A‘raj, who said: “I came to Ibn ‘Abbās while he was resting his head on his cloak at Zamzam. I said to him: ‘Tell me about fasting ‘Āshūrā’.’ He replied: ‘When you sight the crescent of Muharram, count the days, and begin the ninth day fasting.’ I asked: ‘Is this how Muhammad (peace and blessings be upon him) used to fast it?’ He replied: ‘Yes.’”
There is another difficulty: if fasting it was obligatory in the early days of Islam, why did he not instruct them to make it up, since they had missed forming the intention to fast during the preceding night? And if it was not obligatory, how could he instruct those who had already eaten to abstain for the remainder of the day? For the Musnad and the Sunan collections (5) contain reports through several chains of transmission that the Prophet (peace and blessings be upon him) instructed those who had eaten that day to complete the rest of it fasting. This applies only to an obligatory fast. And how can Ibn Mas‘ūd’s statement, “Once fasting Ramadan was prescribed, fasting ‘Āshūrā’ was abandoned,” be correct when fasting it remained recommended?
There is another difficulty: Ibn ‘Abbās identified ‘Āshūrā’ as the ninth day and stated that this was how the Prophet (peace and blessings be upon him) used to fast it. Yet he was also the one who narrated from the Prophet (peace and blessings be upon him): “Fast on the day of
