Umm Salama reported (these words) directly from Allah's Messenger (ﷺ): If anyone has in his possession a sacrificial animal to offer as a sacrifice (on 'Id al-Adha), he should not get his hair cut and nails trimmed after he has entered the first days of Dhu'l Hijja

حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا الأَعْمَشُ، عَنْ أَبِي صَالِحٍ، وَمُجَاهِدٍ، وَمُسْلِمٍ الْبَطِينِ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَا مِنْ أَيَّامٍ الْعَمَلُ الصَّالِحُ فِيهَا أَحَبُّ إِلَى اللَّهِ مِنْ هَذِهِ الأَيَّامِ ‏"‏ ‏.‏ يَعْنِي أَيَّامَ الْعَشْرِ ‏.‏ قَالُوا يَا رَسُولَ اللَّهِ وَلاَ الْجِهَادُ فِي سَبِيلِ اللَّهِ قَالَ ‏"‏ وَلاَ الْجِهَادُ فِي سَبِيلِ اللَّهِ إِلاَّ رَجُلٌ خَرَجَ بِنَفْسِهِ وَمَالِهِ فَلَمْ يَرْجِعْ مِنْ ذَلِكَ بِشَىْءٍ ‏"‏ ‏.‏

Narrated Ibn 'Abbas: The Messenger of Allah (ﷺ) as saying: There is no virtue more to the liking of Allah in any day than in these days, that is, the first ten days of Dhu al-Hijjah. They (the Companions) asked: Messenger of Allah, not even the struggle in the path of Allah (Jihad) ? He said: (Yes), not even the struggle in the path of Allah, except a man who goes out (in the path of Allah) with his life and property, and does not return with any of them.

Abu Qatada reported that a person came to the Messenger of Allah (ﷺ) and said: How do you fast? The Messenger of Allah (ﷺ) felt annoyed. When 'Umar (Allah be pleased with him) noticed his annoyance, he said: We are well pleased with Allah as our Lord, with Islam as our code of life, and with Muhammad as our Prophet. We seek refuge with Allah from the anger of Allah and that of His Messenger. 'Umar kept on repeating these words till his (the Prophet's) anger calmed down. Then Umar said: Messenger of Allah, what is the position of one who fasts perpetually? He (ﷺ) said: He neither fasted nor broke it, or he said: He did not fast and he did not break it. 'Umar said: What about him who fasts for two days and does not fast one day? He (ﷺ) said: Is anyone capable of doing that? He ('Umar) said: What is the position of him who fasts for a day and doesn't fast on the other day? Thereupon he (the Holy Prophet) said: That is the fast of David (peace be upon him). He ('Umar) said: What about him who fasts one day and doesn't fast for two days. Thereupon he (the Messenger of Allah) said: I wish I were given the strength to do that. Thereafter he (ﷺ) said: Fasting three days every month and that of Ramadan every year is a perpetual fasting. I seek from Allah that fasting on the day of 'Arafa may atone for the sins of the preceding and the coming years, and I seek from Allah that fasting on the day of Ashura may atone for the sins of the preceding year.

Abu Qatada al-Ansari (Allah be pleased with him) reported that the Messenger of Allah (ﷺ) was asked about his fasting. The Messenger of Allah (ﷺ) felt annoyed. Thereupon 'Umar (Allah be pleased with him) said: We are pleased with Allah as the Lord, with Islam as our Code of Life, with Muhammad as the Messenger and with our pledge (to you for willing and cheerful submission) as a (sacred) commitment. He was then asked about perpetual fasting, whereupon he said: He neither fasted nor did he break it, or he did not fast and he did not break it. He was then asked about fasting for two days and breaking one day. He (the Holy Prophet) said: And who has strength enough to do it? He was asked about fasting for a day and breaking for two days, whereupon he said: May Allah bestow upon us strength to do it. He was then asked about fasting for a day and breaking on the other, whereupon he said: That is the fasting of my brother David (peace be upon him). He was then asked about fasting on Monday, whereupon he said: It was the day on which I was born. on which I was commissioned with prophethood or revelation was sent to me, (and he further) said: Three days' fasting every month and of the whole of Ramadan every year is a perpetual fast. He was asked about fasting on the day of 'Arafa (9th of Dhu'I-Hijja), whereupon he said: It expiates the sins of the preceding year and the coming year. He was asked about fasting on the day of 'Ashura (10th of Muharram), whereupon be said: It expiates the sins of the preceding year. (Imam Muslim said that in this hadith there is a) narration of Imam Shu'ba that he was asked about fasting on Monday and Thursday, but we (Imam Muslim) did not mention Thursday for we found it as an error (in reporting).
