The Prophet (may Allah's peace and blessings be upon him) liked that a Muslim should perform the deeds he can bear and do regularly. People used to ask about his guidance (may Allah's peace and blessings be upon him) regarding matters confusing and unclear to them, or about things they would like to know, so that they could follow his example and attain success. In this Hadīth, Abu Qatādah al-Ansāri (may Allah be pleased with him) relates that the Messenger of Allah (may Allah's peace and blessings be upon him) was asked about his fasting, meaning: the fasting of the Messenger of Allah (may Allah's peace and blessings be upon him). In the version by Ahmed, it is mentioned that the questioner was a Bedouin, an Arab living in the desert. He (may Allah's peace and blessings be upon him) got angry and the effect of anger became manifest on his face, due to this man's statement and question. He probably got angry because he disliked the question, as he would need to answer it and feared that his answer would lead to some evil, namely that the questioner might think it to be obligatory or too little, or he might restrict himself to it while his condition allowed for more than that. As for the Prophet (may Allah's peace and blessings be upon him), he restricted himself to it due to his preoccupation with the interests and rights of Muslims, and the rights of his wives and guests and those who came to him, lest his example might be followed by anyone, and this would cause harm to some people. The questioner should have said: How much should I fast? Or: How should I fast? Thus, he would pose the question regarding himself, to which he would give him an answer based on his condition, as he gave answers to others on the basis of their respective conditions. Moreover, the Prophet's fasting did not follow one pattern. Rather, it would differ with the difference of conditions. He would sometimes fast often and at other times less often, and a situation like that makes it hard to answer the question. When ‘Umar (may Allah be pleased with him) noticed the Prophet's anger, he - out of politeness and respect towards the Prophet (may Allah's peace and blessings be upon him) and as an apology and appeasement to him, and out of pity towards the questioner - said: "We are pleased with Allah as a Lord, with Islam as a religion, with Muhammad as a Messenger," i.e., we are pleased with His planning and predestination for us, and we have taken Him as our God and Deity, apart from anyone else. And we are pleased with Islam as a religion, as we have chosen it from among all religions and entered it being content and submissive, and we did not seek a religion other than Islam. And we are pleased with Muhammad (may Allah's peace and blessings be upon him) as a Messenger. We are pleased with all he brought from Allah Almighty and accepted that with submission and delight, and we believed what he said, obeyed his commands, and shunned his prohibitions, and we loved, followed, and supported him. "and with our pledge of allegiance as a pledge of allegiance," which refers to the pledge of allegiance over Hijrah and Jihad. This shows complete faith and submission to Allah and to His Messenger and religion. When the Prophet's anger subsided, ‘Umar asked him - as related in another version by Muslim - in a more accurate and rational manner that was closer to the truth. He posed his question in a general way that would benefit all people. He asked him about fasting for all days, which is the fasting for all the days of the year consecutively, and about the state of he who observes such fasts, as to whether it is commendable or dispraised. Thereupon, the Prophet (may Allah's peace and blessings be upon him) said: "May he not fast or break his fast;" or he said: "He has not fasted or broken his fast." The meaning: He does not struggle against the severity of hunger and thirst because he gets used to fasting and so it becomes easier for him, and he does not need the patience over the effort upon which the reward is conditional. Hence, he becomes like one who did not fast. And since he does not gain the comfort and pleasure felt by those who break their fast, it is as if he did not break his fast. It was said: This means supplication against him, by way of deterring him. It may also be an informative statement, meaning that it is as if this person did not break the fast because he ate nothing, and he did not observe the fast because his fast was not prescribed by the Lawgiver. Then, he asked him about a person fasting for two days and not fasting for one day. Thus, the days he fasts are double the days he does not fast, which makes this act of worship more common than the usual way of life. Thereupon, the Prophet (may Allah's peace and blessings be upon him) said: "Who could bear that?!", i.e., who can do that being able to continue fasting while discharging his other duties of the day?! He seemed to have disliked it, for it mostly goes beyond people's capacity, and so it is not encouraged by an easy and tolerant religion. It was said: It indicates that the reason for prohibition is weakness, which means: If anyone can bear it, there is nothing wrong with that. Then, he asked him about a person fasting one day and not fasting for two days. Thus, the days he does not fast are double the days he fasts, and he continues to do that for all his life. The Prophet (may Allah's peace and blessings be upon him) replied to him, saying: I wish that Allah had given us the strength for that. He seemed to have approved of this type of fasting and hoped to observe it. It was said: That his wish pertains to others in his Ummah, for the Prophet (may Allah's peace and blessings be upon him) would bear it and more than that, and it is authentically reported that he (may Allah's peace and blessings be upon him) used to observe continuous fasts. It was said: This means that because of his preoccupation with his wives, guests, activities, and people, the Messenger of Allah (may Allah's peace and blessings be upon him) did not observe this amount of fasting on a continuous basis. This is not because of his weakness to bear fasting, or his lack of patience over abstinence from eating for this period. Then, he asked him about a person who fasts one day and does not fast for one day, and who takes that as a habit. In response, the Prophet (may Allah's peace and blessings be upon him) said: "That is the fasting of my brother David (Dāwūd) (peace be upon him)." This indirectly indicates that the Messenger of Allah (may Allah's peace and blessings be upon him) encouraged this fasting, for it is very moderate and it takes the two aspects of worship and habit into the best consideration, and it is one of the most beloved fasts to Allah Almighty, as related in the Two Sahīh Collections. This is because it is not ongoing fasting nor ongoing abandonment of fasting. Then, he asked him about the reason behind fasting on Monday. Thereupon, the Prophet (may Allah's peace and blessings be upon him) said: "That is the day on which I was born and a day on which I was commissioned (as a Prophet)," i.e., the day of the beginning of my prophethood; so, it is the day most worthy of being fasted. Or he said: "the revelation was sent down to me therein;" the revelation began to come down on it. Then, the Prophet (may Allah's peace and blessings be upon him) said that fasting three days every month - which applies to specification, like the fasting of the white days: the 13th, 14th, and 15th days; or to generality, like fasting three days at the beginning of the month, its middle, or at its end, successively or sporadically - and the fasting of Ramadan every year is equivalent to the fasting of all days. That is, Allah, out of His grace and generosity, multiplies the reward for every act of goodness and worship, involving words or deeds, tenfold. So, a good deed is multiplied to ten similar good deeds. Likewise, the fasting of one day is recorded as fasting of ten days. Accordingly, if a person fasts three days, it is as if he fasts thirty days, which is a whole month. Thus, by fasting three days every month, it is as if he fasts the entire year, in addition to the obligatory fasting in the month of Ramadan. And he asked him about fasting on the day of ‘Arafah. In response, the Prophet (may Allah's peace and blessings be upon him) said that whoever fasts it, Allah forgives for him the sins of two years: the past year and the coming year. This fasting is to be observed by non-pilgrims, for it is disliked for a pilgrim to fast on the day of ‘Arafah. This is because fasting on this day will make the pilgrim too weak to stand and supplicate. As for non-pilgrims, they are addressed by this Hadīth to the relevant merit and attainment of rewards from Allah Almighty. The day of ‘Arafah is the ninth day of Dhul-Hijjah. It was called as such because it comprises one of the pillars of Hajj, namely standing at ‘Arafah in Makkah. Then, he asked him about the fasting of the day of ‘Āshūrā’, which is the tenth day of the month of Muharram. This is the day in which Allah saved Moses (peace be upon him) and his people from Pharaoh. So, Moses fasted it in gratitude to Allah for His favor in destroying the oppressors. In response, he (may Allah's peace and blessings be upon him) said that Allah forgives by fasting this day the sins of the past year. This expiation includes minor sins, not the major ones. As for major sins, they can only be expiated by repentance or mercy from Allah, or it is hoped the major sins will be alleviated. It was said: The expiation for the coming year is that He will preserve him from committing sins in it. It was also said: that He will give him an amount of mercy and reward that expiates for the past year and the next one if it comes and he commits sins therein. These questions by ‘Umar (may Allah be pleased with him) point to his proper understanding. He first calmed the anger of the Prophet (may Allah's peace and blessings be upon him) and then asked him about certain types of fasting that comprise all that a Muslim can observe, and he knew their rulings, while demonstrating which of them are valid and which are not and pointing out the merit of some of them. Meanwhile, he taught us all of that. So, whoever wishes can observe the valid fast and choose what is more suitable for himself and his ability. The Hadīth points out the merit of fasting on Monday. It also points out the merit of fasting on the day of ‘Āshūrā’. It also shows the merit of fasting on the day of ‘Arafah. And it demonstrates the merit of fasting during the month of Ramadan. The Hadīth points out that Allah is Kind to His servants, and He facilitates things for them and removes hardships and restrictions from them. The Hadīth prohibits fasting for all days. And it forbids overburdening oneself in worship with things beyond one's capacity..
