Hakam bin A'raj narrates that I asked Sayyiduna Ibn Abbas (may Allah be pleased with them both) while he was sitting in the Sacred Mosque, reclining on his cloak. I asked him about the fasting of Ashura. He said: "Keep counting, and when you reach the morning of the ninth of Muharram, then fast." He says: I asked, "Did Muhammad (peace be upon him) used to fast like this?" He replied, "He used to fast like this."

It is narrated with the chain of narration from Ja'far bin Muhammad similar to the above, with these words: He was sitting near Zamzam, making his cloak a pillow.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that he said regarding the day of Ashura that it is the ninth day. I asked, "So did Muhammad (peace be upon him) also fast on (the ninth day) like this?"
