This hadith has been narrated by Ibn Abu Khalid with the same chain of transmitters.

We saw the new moon of Ramadan as we were at Dhit-i-'Irq. We sent a man to Ibn Abbas (Allah be pleased with both of them) to ask him (whether the sighting of a small moon had something of the nature of defect in it). Upon this Ibn 'Abbas (Allah be pleased with both of them) said that the Messenger of Allah (ﷺ) had said: Verily Allah deferred its sight, but if (the new moon) is hidden from you, then, complete its number (thirty).

I heard the Messenger of Allah (ﷺ) as saying: Bilal announces Adhan during the night, so you eat and drink, till you hear the Adhan of Ibn Umm Maktum.

Bilal announces Adhan at (the fag end of the) night (i. e. Sahri), so eat and drink till the son of Umm Maktum announces Adhan. And he (the narrator) said: And the (difference of time) between their (Adhans) was not more than this that one climbed down (from the minaret) and the other climbed up (to announce Adhan).

The dawn is not like it, as one says (and he lifted his hand) till he (dispersed his fingers) and said: It is like this.

The dawn is not like it as it is said; he then gathered his fingers and lowered them. But he said, it is like this (and he placed the index finger upon the other one and spread his hand).

Samura b. Jandub reported Muhammad (ﷺ) as saying. The call of Bilal may not mislead any one of you (and he may, under the wrong impression gathered from it, refrain) from taking meal before the commencement of the fast (for the streaks) of this whiteness (which are vertical indicate the false dawn and the true dawn with which the fast commences is that when the streaks of light are) spread.

The Adhan of Bilal may not mislead you with regard to your food at the commencement of the fast, nor the vertical (streaks) of whiteness in the horizon (for it is an indication of false dawn). You should stop eating (food) till (the whiteness) spreads like it. Hammad narrated it and with the gesture of his band he explained, the horizontal position (of the streaks of light).

We took meal shortly before dawn along with the Messenger of Allah (ﷺ). We then stood up for prayer. I said: How much span of time was there between the two (acts, i. e. taking of Sahri and observing of prayer)? He said (a span of reciting) fifty verses.

The people will continue to prosper as long as they hasten the breaking of the fast.

I and Misruq went to 'A'isha (Allah be pleased with her) and Masruq said to her: There are two persons among the Companions of Muhammad (ﷺ) none of whom abandons the good, but one of them hastens to observe sunset prayer and break the fast, and the other delays in observing the sunset prayer and in breaking the fast, whereupon she said: Who hastens to observe sunset prayer and break the fast? He said: It is 'Abdullah. Upon this she said: This is how the Messenger of Allah (ﷺ) used to do.

We travelled with the Messenger of Allah (ﷺ) as he had been observing fast. When the sun sank he said: So and so, get down and prepare barley meal for us. The rest of the hadith is the same.

This hadith is narrated on the authority of Hisham with the same chain of transmitters, but he made no mention in the first part of the hadith that the Messenger of Allah (ﷺ) used to observe fast, and said about the second part that he abandoned the (fast) of Ashura, and he who wished observed the fast and who wished otherwise abandoned it, and he did not hold it as the words of the Messenger of Allah (ﷺ) as mentioned in the narration transmitted by Jarir.

People of Medina, where are your scholars? I heard the Messenger of Allah (ﷺ) say on this very day: It is the day of 'Ashura. Allah has not made fasting on This day obligatory for you but I am fasting. He who likes to observe fast among you should do so, and he who likes not to observe it may not observe it.

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

You (only) observe fast on this day.

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

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.

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."

'A'isha (Allah be pleased with her) said that the Prophet (ﷺ) forbade to observe fast on two days-the day of Fitr and the day of Adha.
