Fasting on the day of Arafah

Sayyidah Aishah al-Siddiqah (may Allah be pleased with her) narrated: The Prophet (peace and blessings be upon him) forbade the people at Arafat from fasting on the day of Arafah.
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat. Its chain contains a narrator, Muhammad bin Abi Yahya, about whom much has been said, although he has been declared trustworthy.

Sayyiduna al-Fadl bin Abbas (may Allah be pleased with them both) narrated: I saw the Prophet (peace and blessings be upon him) on the day of Arafah; he drank a drink.
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir, and its narrators are the narrators of the Sahih.
Imam Abu Ya'la recorded it similarly.

Ata' al-Khurasani narrated: Sayyiduna Abd al-Rahman bin Abi Bakr (may Allah be pleased with him) came to Sayyidah Aishah (may Allah be pleased with her) on the day of Arafah while she was fasting and water was being sprinkled on her. Sayyiduna Abd al-Rahman (may Allah be pleased with him) said to her: "Break your fast." Sayyidah Aishah (may Allah be pleased with her) said: "Should I break my fast when I have heard the Prophet (peace and blessings be upon him) say: 'Fasting on the day of Arafah becomes an expiation for the sins of the year before it'?"
Imam Ahmad recorded it. The narrator Ata' did not hear from Sayyidah Aishah (may Allah be pleased with her); rather, Yahya bin Ma'in said: To my knowledge he did not meet any of the Companions. The remaining narrators of this report are the narrators of the Sahih.

Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) narrated: The Prophet (peace and blessings be upon him) said: "Whoever fasts on the day of Arafah, the sins of two consecutive years are forgiven for him."
Imam Abu Ya'la and Imam al-Tabarani in al-Mu'jam al-Kabir recorded it. The narrators of Imam Abu Ya'la are the narrators of the Sahih.

Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrated: The Prophet (peace and blessings be upon him) said: "Whoever fasts on the day of Arafah, the sins of one past year and one coming year are forgiven for him; and whoever fasts on the day of Ashura, the sins of one year are forgiven for him."
Imam al-Bazzar recorded it. Its chain contains a narrator, Umar bin Suhban, and he is matruk (abandoned).
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat in abridged form, leaving out the day of Ashura, and Imam al-Tabarani's chain is hasan (good).

Masruq narrated that he came to Sayyidah Aishah (may Allah be pleased with her) on the day of Arafah and said: "Give me something to drink." Sayyidah Aishah (may Allah be pleased with her) said: "O boy, give him honey to drink." Then Sayyidah Aishah (may Allah be pleased with her) said: "O Masruq, are you not fasting?" He replied: "No, I feared that it might be the day of sacrifice." Sayyidah Aishah (may Allah be pleased with her) said: "That is not so. The day of Arafah is the day which the Imam (i.e. the ruler of the time) has declared to be the day of Arafah, and the day of sacrifice is the day which the Imam (i.e. the ruler of the time) has declared to be the day of sacrifice. O Masruq! Have you not heard that the Prophet (peace and blessings be upon him) used to regard this day as equal to a thousand days?"
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat. Its chain contains a narrator, Dalham bin Salih, whom Yahya bin Ma'in and Ibn Hibban declared da'if (weak).

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrated: The Prophet (peace and blessings be upon him) said: "Whoever fasts on the day of Arafah, it becomes an expiation for him for (the sins of) two years; and whoever fasts one day of Muharram receives, for each day, the reward of thirty days."
Imam al-Tabarani recorded it in al-Mu'jam al-Saghir. Its chain mentions that al-Haytham bin Habib narrated it from Sallam al-Tawil. The narrator Sallam is da'if (weak). As for al-Haytham bin Habib, I have not seen anyone other than al-Dhahabi speak about him; al-Dhahabi accused him on account of a report that he narrated. Ibn Hibban declared him thiqah (trustworthy).

Sa'id bin Jubayr narrated: A man asked Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) about fasting on the day of Arafah. He replied: "When we were with the Prophet (peace and blessings be upon him), we used to regard this day as equal to fasting two years." (Allamah al-Haythami says:) I say: Imam al-Nasa'i (may Allah have mercy on him) recorded this report from him
with the wording that they regarded it as equal to fasting one year.
Imam al-Tabarani recorded it in al-Mu'jam al-Awsat, and its chain is hasan (good).

Sayyiduna Zayd bin Arqam (may Allah be pleased with him) reports from the Prophet (peace and blessings be upon him) that he was asked about fasting on the day of Arafah, and he said: "It becomes an expiation for the year in which you are, and (it becomes an expiation) for the year after it as well."
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir. Its chain contains a narrator, Rishdin bin Sa'd, about whom criticism has been made, although he has been declared trustworthy.
