Hazrat Ulaylah bint Kameet Atkiyyah narrates that I heard my mother Amina relate a narration similar to the above hadith, and in it there is this addition: So Allah Almighty sufficed those suckling infants. Janab Muslimah narrates that their mother was a servant of the Prophet Muhammad (peace be upon him), who was called Razinah.

It is narrated from Sayyiduna Muhammad bin Saifi (may Allah be pleased with him) that he states: On the day of Ashura, the Messenger of Allah (peace and blessings be upon him) came to us and said: "Have you fasted today?" Some said, "Yes, we have fasted." And some individuals said, "No, we have not." The Prophet (peace and blessings be upon him) said: "Then complete the fast for the rest of this day." And he instructed them: "Inform the villages located in the outskirts of Madinah as well, that they should complete the fast for the rest of the day."

It is narrated from Sayyiduna Salamah bin Akwa’ (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said to a man from the tribe of Aslam:“Announce among your people or among the people on the day of ‘Ashura that whoever has eaten should fast for the rest of the day, and whoever has not eaten should observe the fast.”

The narration of Sayyiduna Abu Sa'id Khudri, Muhammad bin Sayghi Ansari, Abdullah bin Minhal Khuza'i (may Allah be pleased with them) from his uncle, and the narrations of Asma bint Haritha and Sayyiduna Abdullah Juhani (may Allah be pleased with them) are related to the same issue. I have mentioned it in Kitab al-Kabir.

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Today is the day of Ashura, so whoever wishes may fast on this day, and whoever wishes may not fast." The narrations of Sayyidah Aisha and Muawiyah (may Allah be pleased with them both) are also related to this issue.

Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Fast on the day of Ashura and oppose the Jews; fast a day before it or a day after it as well."

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.
