A hadith like this has been narrated on the authority of Ibn Shihab through the same chain of transmitters.

I am fasting today, so he who wishes to observe fast should do so; but he did not make mention of the rest of the hadith.

It is the day on which Allah granted victory to Moses and (his people) Bani Isra'il over the Pharaoh and we observe fast out of gratitude to Him. Upon this the Messenger of Allah (ﷺ) said: We have a closer connection with Moses than you have, and he commanded to observe fast on this day.

This hadith has been narrated by Ibn Bishr with the same chain of transmitters (but with a slight variation) that he (the Holy Prophet) inquired of them (Jews) about it (fasting on the day of 'Ashura).

What is the (significance) of this day that you observe fast on it? They said: It is the day of great (significance) when Allah delivered Moses and his people, and drowned the Pharaoh and his people, and Moses observed fast out of gratitude and we also observe it. Upon this the Messenger of Allah (ﷺ) said: We have more right, and we have a closer connection with Moses than you have; so Allah's Messenger (ﷺ) observed fast (on the day of 'Ashura), and gave orders that it should be observed.

This hadith has been narrated on the authority of Ayyub with the same chain of transmitters.

The day of 'Ashura was one which the Jews respected and they treated it as Id. The Messenger of Allah (ﷺ) said: You also observe fast on this day.

You (only) observe fast on this day.

I do not know Allah's Messenger (ﷺ) singling out any day's fast and considering it more excellent than another, except this day (the day of Ashura) and this month, meaning the month of Ramadan.

A hadith like this has been narrated on the authority of 'Ubaidullah b. Abi Yazid.

I went to Ibn 'Abbas (Allah be Pleased with both of them) and he was reclining using his mantle as a pillow near the fountain of Zamzam. I said to him: Tell me about fasting on Ashura. He said: When you see the new moon of Muharram then count the (days) and observe fast on the 9th. I said to him: Is it how the Messenger of Allah (ﷺ) observed the fast? He said: Yes.

I asked Ibn Abbas (Allah be pleased with them) as he was reclining using his cloak as a pillow near Zamzam about fasting on 'Ashura. The rest of the hadith is the same.

Messenger of Allah, it is a day which the Jews and Christians hold in high esteem. Thereupon the Messenger of Allah (ﷺ) said: When the next year comes, God willing, we would observe fast on the 9th But the Messenger of Allah (ﷺ) died before the advent of the next year.

If I live till the next (year), I would definitely observe fast on the 9th, and the narration transmitted by Abu Bakr is:" He meant the day of Ashura."

Salama b. al-Akwa' (Allah be pleased with him) reported that the Messenger of Allah (ﷺ) sent a person of the tribe of Aslam on the day of 'Ashura and commanded him to declare to the people to observe fast in case they had not observed it, and to complete fast till evening if they had taken food

He who got up in the morning fasting (without eating anything) he should complete his fast, and he who had had his breakfast in the morning, he should complete the rest of the day (without food). The Companions said; We henceforth observed fast on it (on the day of 'Ashura) and, God willing, made our children observe that. We went to the mosque and made toys out of wool for them and when anyone felt hungry and wept for food we gave them these toys till it was the time to break the fast.

I asked Rubayyi' daugther of Mu'awwidh about fasting on the day of 'Ashura. Thereupon she said: The Messenger of Allah (may peace he upon him) sent his messenger to the villages of the Ansar, and the rest of the hadith is the same (but with this variation that one of the Companions) said:" We used to make toys out of wool and took (them to the mosque) along with us. When they (the children) asked us for food, we gave them these toys to play with, and these made them forgetful till they completed their fast."

I observed Id along with Umar b. al-Khattab (Allah be pleased with him). He came (out in an open space) and prayed and (after) completing it addressed the people and said: The Messenger of Allah (ﷺ) has forbidden the observing of fast on these two days. One is the day of Fitr (at the end of your fasts), and the second one, the day when you eat (the meat) of your sacrifices.

Abu Huraira (Allah be pleased with him) reported that the Messenger of Allah (ﷺ) forbade fasting on these two days. 'Id-ul-Adha and 'Id-ul-Fitr.

I heard from him (Abu Sa'id) a hadith which impressed me, and I said to him: Did you hear it from the Messenger of Allah (ﷺ)? Thereupon he said: (Is it possible) that (I should) say about the Messenger of Allah (ﷺ) that which I have not heard? I heard him saying: It is not proper to fast on two days, Adha and Fitr (at the end) of Ramadan.
