Narrated by Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with him), he says: I presented myself before the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah! Command me regarding fasting. The Prophet (peace and blessings be upon him) said: Fast one day, and you will receive the reward of an additional nine days (because the reward of every good deed is tenfold). I said: O Messenger of Allah! I have the strength for more than this, so grant me permission to fast more. The Prophet (peace and blessings be upon him) said: Fast two days, and you will receive the reward of an additional eight days. But I again said: O Messenger of Allah! I have the strength for more than this, so grant me permission for more fasting. The Prophet (peace and blessings be upon him) said: Fast three days, and you will receive the reward of an additional seven days. But with my repeated requests, the Prophet (peace and blessings be upon him) kept allowing for more action (and reducing the reward), until the Prophet (peace and blessings be upon him) said: The best fasts are those of my brother Dawud (peace be upon him), and that is to fast one day and leave one day. When Sayyiduna Abdullah became old, he used to say: I wish I had sufficed with the first command of the Noble Prophet (peace and blessings be upon him).

(Second chain) It is narrated from Sayyiduna Abdullah bin Amr, may Allah be pleased with him, ... narrated in the same manner as the previous hadith ... , further in this it is mentioned: Sayyiduna Abdullah, may Allah be pleased with him, continued to fast in this way until he became old and weak, at that time he used to say: If I had accepted the concession given by the Messenger of Allah, peace and blessings be upon him, it would have been more beloved to me than my family, wealth, and property.

A wife of the Messenger of Allah (may Allah be pleased with her) narrates that the Messenger of Allah (peace and blessings be upon him) used to fast the first nine days of Dhul-Hijjah, the Day of Ashura, and three days in every month.

It is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Fasting on the Day of Arafah, that is, the 9th of Dhul-Hijjah, becomes an expiation for the sins of the previous and the coming two years, and fasting on the Day of Ashura is an expiation for the sins of the previous year.

. Sayyiduna Abdur Rahman bin Abi Bakr went to Sayyidah Aisha (may Allah be pleased with them both) on the day of Arafah while she was fasting, and (due to the intensity of the heat) water was being poured over her. Sayyiduna Abdur Rahman (may Allah be pleased with him) said to her: "You should break your fast," but she replied: "How can I break my fast, when I heard the Messenger of Allah (peace and blessings be upon him) say: 'The fast of Arafah is an expiation for the sins of the previous year.'"

Mawla Ibn Abbas, Hazrat Ikrimah says: I visited Sayyiduna Abu Hurairah (may Allah be pleased with him) at his home and asked him about fasting on the Day of Arafah. He said: The Messenger of Allah (peace and blessings be upon him) forbade fasting on the Day of Arafah in the plain of Arafat.

Saeed bin Jubair says: I went to Abdullah bin Abbas (may Allah be pleased with him) at the place of Arafah, while he was eating pomegranate. He said to me: Come closer and eat, but it seems that you are fasting. The Messenger of Allah (peace and blessings be upon him) did not fast on this day. And on one occasion he said that the Messenger of Allah (peace and blessings be upon him) did not fast on this day.

Nafi' reports that it was asked from Sayyiduna Abdullah bin Umar (may Allah be pleased with him) about the fast of the Day of Arafah.

(Second chain) A man asked Sayyiduna Abdullah bin Umar (may Allah be pleased with him) about fasting on the Day of Arafah. He said: We set out for Hajj with the Messenger of Allah (peace and blessings be upon him), and he did not fast on that day. Then we came with Sayyiduna Abu Bakr (may Allah be pleased with him), and he also did not fast. Then we came with Sayyiduna Umar (may Allah be pleased with him), and he also did not fast on that day. Then we came with Sayyiduna Uthman (may Allah be pleased with him), and he also did not fast on that day. Therefore, I also do not fast on that day, but I neither command you to fast nor forbid you from it. If you wish, you may fast, and if you wish, you may not fast.
