Ibn Abbas (RA) was asked about observing of fast on the day of Ashura, whereupon he said: 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 bin Abi Yazid.

Ibn 'Abbas reported: Allah's Messenger (ﷺ) sent me from Muzdalifa ahead (of the caravan) along with the luggage or with the weak ones during (the latter part of the) night.

Ibn 'Abbas (RA) reported: I was among those (i. e. women and children) whom Allah's Messenger (ﷺ) sent forth with the weak members of his family.

Ubaidullah bin Abu Yazid heard Ibn 'Abbas (RA) as saying: Usama bin Zaid reported Allah's Apostle (ﷺ) as saying: There can be an element of interest in credit (when the payment is not equal).

Abu Hurairah (RA) reported Allah's Messenger (ﷺ) as saying to Hasan: O Allah, behold, I love him. Thou too love him and love one who loves him.

Abu Hurairah (RA) reported: I went along with Allalh's Messenger (ﷺ) at a time during the day but he did not talk to me and I did not talk to him until he reached Bazar of Bani Qainuqa'. He came back to the tent of Fatima and said: Is the little chap (meaning Hasan) there? We were under the impression that his mother had detained him in order to bathe him and dress him and garland him with a sweet garland. Not much time had passed that he (Hasan) came running until both of them embraced each other, thereupon Allah's Messenger (ﷺ) said: O Allah, I love him; love him Thou and love one who loves him (Hasan).

Ibn 'Abbas reported that Allah's Messenger (ﷺ) came to privy and I placed for him water for ablution, When he came out he said: Who placed it here? And in a version of Zuhair they (the Companions) said, and in the version of Abu Bakr (RA) (the words are): I said: It is Ibn 'Abbas (who has done that), whereupon he (the Holy Prophet) said: May Allah grant him deep understanding of religion.

And it was narrated to me by Zuhayr ibn Harb, who said: Sufyan ibn ‘Uyaynah narrated to us, from ‘Ubaydullah ibn Abi Yazid, from Mujahid, from Ibn Abi Layla, from ‘Ali ibn Abi Talib.

And it was also narrated to us by Muhammad ibn ‘Abdullah ibn Numayr and ‘Ubayd ibn Ya‘ish, from ‘Abdullah ibn Numayr, who said: ‘Abd al-Malik narrated to us, from ‘Ata’ ibn Abi Rabah, from Mujahid, from Ibn Abi Layla, from ‘Ali, from the Prophet, peace and blessings be upon him, with a narration similar to that of al-Hakam, from Ibn Abi Layla, and he added in the narration: ‘Ali said: “I have not abandoned it since I heard it from the Prophet, peace and blessings be upon him.” It was said to him: “Not even on the night of Siffin?” He said: “Not even on the night of Siffin.” And in the narration of ‘Ata’, from Mujahid, from Ibn Abi Layla, he said: I said to him: “Not even on the night of Siffin?”
