Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Abu Qatadah that the Messenger of Allah, peace and blessings be upon him, said: Fasting on the Day of Arafah is an expiation for the sins of two years, one for the past year and one for the coming year.

Hazrat Abu Qatadah narrates that the Noble Prophet (peace and blessings be upon him) was asked about the fast of the Day of Arafah. He replied that consider the fast of the Day of Arafah as an expiation for the sins of two years: one for the past year's sins and one for the coming year's sins.

Hazrat Aisha (may Allah be pleased with her) used to fast on the Day of Arafah.

Hazrat Aisha (may Allah be pleased with her) said that throughout the year, the day I like most for fasting is the Day of Arafah.

It is narrated from Hazrat Sahl bin Sa’d that the Messenger of Allah, peace and blessings be upon him, said: Fasting on the day of Arafah is an expiation for the sins of two years.

Hazrat Qasim used to fast on the Day of Arafah.

Ibrahim, regarding fasting on the Day of Arafah in the sacred precinct, says that if there is any disagreement about it, then one should by no means fast.

Ibrahim states that the predecessors did not consider there to be any harm in fasting on the Day of Arafah; however, if there is a fear that it might be the Day of Sacrifice (Yawm al-Nahr), then one should not fast on that day.

Hazrat Aisha (may Allah be pleased with her) says that the fast of Arafah is an expiation for the sins of half a year. Hazrat Mujahid says that it is an expiation for the sins of one year.

Hazrat Humaid al-Tawil says that once it was mentioned before Hasan that the reward for fasting on the Day of Arafah is equal to the reward of fasting for a whole year. Upon hearing this, Hasan said that in my opinion, no day has any superiority over another day. And except for Laylat al-Qadr, no night has any superiority over another night. The Night of Qadr is better than a thousand nights. I saw Hazrat Uthman bin Abi al-As that he used to fast on the Day of Arafah, and due to the intense heat, water would be sprinkled on him for coolness.
