This hadith has been narrated by Ibn Bishr with the same chain of transmitters (but with a slight variation) that he (the Holy Prophet) inquired of them (Jews) about it (fasting on the day of 'Ashura).

The people doubted whether Allah's Apostle was fasting or the Day of `Arafat or not. So I sent a cup containing milk to him and he drank it.

I was with Ibn `Umar when a man asked him, "I have vowed to fast every Tuesday or Wednesday throughout my life and if the day of my fasting coincided with the day of Nahr (the first day of `Id-al- Adha), (What shall I do?)" Ibn `Umar said, "Allah has ordered the vows to be fulfilled, and we are forbidden to fast on the day of Nahr." The man repeated his question and Ibn `Umar repeated his former answer, adding nothing more.

Abu Huraira (Allah be pleased with him) reported that the Messenger of Allah (may peace be upon him) forbade fasting on these two days. 'Id-ul-Adha and 'Id-ul-Fitr.

that the people were in doubt whether the Prophet was fasting on the Day of `Arafat or not, so a (wooden) drinking vessel full of milk was sent to him, and he drank it.

When the Divine Revelation: "For those who can fast, they had a choice either fast, or feed a poor for every day," (2.184) was revealed, it was permissible for one to give a ransom and give up fasting, till the Verse succeeding it was revealed and abrogated it.

The people doubted whether the Prophet was fasting on the day of `Arafat or not, so I sent milk while he was standing at `Arafat, he drank it and the people were looking at him.

The Prophet (saws) said: The month consists of twenty-nine days, but do not fast till you sight it (the moon) and do not break your fast till you sight it. If the weather is cloudy, calculate it thirty days. When the twenty-ninth of Sha'ban came, Ibn Umar would send someone (who tried) to sight the moon for him. If it was sighted, then well and good; in case it was not sighted, and there was no cloud and dust before him (on the horizon), he would not keep fast the next day. If there appeared (on the horizon) before him cloud or dust, he would fast the following day. Ibn Umar would end his fasting alone with the people, and did not follow this calculation.

My father got me married to a lady of a noble family, and often used to ask my wife about me, and she used to reply, "What a wonderful man he is! He never comes to my bed, nor has he approached me since he married me." When this state continued for a long period, my father told the story to the Prophet who said to my father, "Let me meet him." Then I met him and he asked me, "How do you fast?" I replied, "I fast daily," He asked, "How long does it take you to finish the recitation of the whole Qur'an?" I replied, "I finish it every night." On that he said, "Fast for three days every month and recite the Qur'an (and finish it) in one month." I said, "But I have power to do more than that." He said, "Then fast for three days per week." I said, "i have the power to do more than that." He said, "Therefore, fast the most superior type of fasting, (that is, the fasting of (prophet) David who used to fast every alternate day; and finish the recitation of the whole Qur'an In seven days." I wish I had accepted the permission of Allah's Apostle as I have become a weak old man. It is said that `Abdullah used to recite one-seventh of the Qur'an during the day-time to some of his family members, for he used to check his memorization of what he would recite at night during the daytime so that it would be easier for him to read at night. And whenever he wanted to gain some strength, he used to give up fasting for some days and count those days to fast for a similar period, for he disliked to leave those things which he used to do during the lifetime of the Prophet.

Sometimes Allah's Apostle would not fast (for so many days) that we thought that he would not fast that month and he sometimes used to fast (for so many days) that we thought he would not leave fasting throughout that month and (as regards his prayer and sleep at night), if you wanted to see him praying at night, you could see him praying and if you wanted to see him sleeping, you could see him sleeping.

When the Prophet arrived at Medina, he noticed that some people among the Jews used to respect Ashura' (i.e. 10th of Muharram) and fast on it. The Prophet then said, "We have more right to observe fast on this day." and ordered that fasting should be observed on it.

Umm al-Fadl (Allah be pleased with her) is reported to have said that some people among the Companions of the Messenger of Allah (may peace be upon him) were in doubt about fasting on the day of 'Arafa and we were with him on that day. I (Umm al-Fadl) sent him a cup of milk and he was halting at 'Arafa, and he drank that.

Yahya related to me from Malik from Yazid ibn Abdullah ibn al- Hadi from Abu Murra, the mawla of Umm Hani, the sister of Aqil ibn Abi Talib, that Abdullah ibn Amr ibn al-As told him that he had visited his father Amr ibn al-As and found him eating. His father had invited him to eat, and when he replied that he was fasting, his father said, "These are the days on which the Messenger of Allah, may Allah bless him and grant him peace, forbade us to fast, and told us to break the fast on them."

Malik said, "These days are the days of tashriq."

Yahya related to me from Malik from Abu'n-Nadr, the mawla of Umar ibn Ubaydullah, from Sulayman ibn Yasar that the Messenger of Allah, may Allah bless him and grant him peace, forbade fasting on the days of Mina.

Some food was presented to me and Hafsah. We were fasting, but broke our fast. Then the Messenger of Allah (saws) entered upon us. We said to him: A gift was presented to us; we coveted it and we broke our fast. The Messenger of Allah (saws) said: There is no harm to you; keep a fast another day in lieu of it.

Two fasts and two kinds of sale are forbidden: fasting on the day of `Id ul Fitr and `Id-ul-Adha and the kinds of sale called Mulamasa and Munabadha. (These two kinds of sale used to be practiced in the days of Pre-Islamic period of ignorance; Mulamasa means when you touch something displayed for sale you have to buy it; Munabadha means when the seller throws something to you, you have to buy it.)

Allah's Apostle forbade Al-Wisal (fasting continuously for more than one day without taking any meals). A man from the Muslims said, "But you do Al-Wisal, O Allah's Apostle!" Allah's Apostle I said, "Who among you is similar to me? I sleep and my Lord makes me eat and drink." When the people refused to give up Al-Wisal, the Prophet fasted along with them for one day, and did not break his fast but continued his fast for another day, and when they saw the crescent, the Prophet said, "If the crescent had not appeared, I would have made you continue your fast (for a third day)," as if he wanted to punish them for they had refused to give up Al-Wisal.

I came to the Prophet and he said to me, "Come near." So I went near to him and he said, "Are your lice troubling you?" I replied, "Yes." He said, "(Shave your head and) make expiation in the form of fasting, Sadaqa (giving in charity), or offering a sacrifice." (The sub-narrator) Aiyub said, "Fasting should be for three days, and the Nusuk (sacrifice) is to be a sheep, and the Sadaqa is to be given to six poor persons."

Yahya related to me from Malik that Yahya ibn Said said, "I have heard that by his good character a man can reach the degree of the one who stands in prayer at night and the one who is thirsty from fasting in the heat of the day."

Hunaydah al-Khuza'i reported on the authority of her mother who said: I entered upon Umm Salamah and asked her about fasting. She said: The Messenger of Allah (saws) used to command me to fast three days every month beginning with Monday or Thursday.

'A'isha (Allah be pleased with her) reported. In the pre-Islamic days fast was observed on the day of Ashura, but with the advent of Islam (its position was ascertained as that of a voluntary fast). Then he who wished to fast fasted, and he who liked to abandon it abandoned it.

I asked `Aisha "Did Allah s Apostle, use to choose some special days (for fasting)?" She replied, "No, but he used to be regular (constant) (in his service of worshipping). Who amongst you can endure what Allah's Apostle used to endure?"

Jabir b Samura reported that the Messenger of Allah (may peace be upon him) commanded us to observe fast on the day of Ashura and exhorted us to do it and was particular about it But when (fasting) in Ramadan was made obligatory, he hence. forth neither commanded us nor forbade us, nor was he so particular about it.

Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, forbade fasting for two days or more without breaking the fast in between. They said, "But Messenger of Allah, you practise wisal." He replied, "I am not the same as you. I am fed and given to drink."

Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to say, "If some one makes himself vomit while he is fasting he has to make up a day, but if he cannot help vomiting he does not have to make up anything."

We set out with Allah's Apostle on one of his journeys on a very hot day, and it was so hot that one had to put his hand over his head because of the severity of heat. None of us was fasting except the Prophet and Ibn Rawaha.
