* ARAFFA day.
The one who abandons the burning from the fire, and the day of Arafat is one of the best days of the ten, but one of the best days of the year.
Also, God is one of us in whom we abundantly release his glory, as mentioned in Sahih Muslim
He said :
 (Aisha said that the Messenger of Allah, peace be upon him, said that more than a day that God frees the slaves from the fire from the day of Arafa and it's approaching and then boast of their angels says what they wanted). narrated by Muslim
Modern:
(I reckon that God will expiate the Sunnah that came before him and the Sunnah after him) Sahih Muslim
The best of supplication is the supplication of the Day of Knowledge (there is no god but God alone, there is no partner for whom the King is glorified, praise and He is above all able) .....
* As for fasting on the day of Arafat, which is the ninth day of Dhu al-Hijjah, the Prophet, peace and blessings be upon him, was asked about his fasting and he said:
Modern:
(I reckon that God will expiate the Sunnah that came before him and the Sunnah after him) Sahih Muslim
It is necessary to know that it is mustahabb to fast on the day of 'Arafah, but it is only for the pilgrim. As for the pilgrim, his fasting is not prescribed for him, because the Prophet, may God’s prayers and peace be upon him, did not fast in Arafat, but forbade it, for Abu Huraira, may God be pleased with him, said: “The Messenger of God, may God bless him and grant him peace, said: On Fasting on the Day of Arafat in Arafat) (Sahih on the condition of Bukhari)

Ten takbeers of Dhu al-Hijjah

*. Performing the Hajj.
Performing the Hajj, because of the great merit
1- Hajj is one of the best works.
The Prophet, peace be upon him, was asked about the best work
He said: Iman, Allah and His Messenger. "It was said: Then what? He said: Jihad for the sake of God - It was said: Then what? He said: Hajj is justified....
2- It denies poverty and sins
Interview (followed between the Hajj and Umrah, they eliminate poverty and sins as the bellows eliminate impurities from iron, gold and silver, not the argument Almbrorh, "said Abu crepe: Hajj Emperor, without the reward of Paradise) isnaad Hassan
3- That the justified Hajj and its rewards are Paradise.
The hadeeth: On the authority of Abu Hurairah - may God be pleased with him - that the Messenger of God - may God’s prayers and peace be upon him - said: “Umrah to Umrah is an atonement for what is between them, and the compelling Hajj is obligatory.”
4- The remission of sins and sins committed by man throughout his life
(He who performs Hajj to God did not be exalted and did not commit debauchery, and he returned as the day his mother gave birth to
him) Narrated by Al-Bukhari

* From works in the ten days of Dhul Hijjah.
* The sacrifice.
God made the sacrifice
(فَصَلِّ لِرَبِّكَ وَانْحَرْ) Kawthar: 2
The hadeeths: In Sahih and others, on the authority of Anas, may God be pleased with him, he said:...
“The Prophet, may God’s prayers and peace be upon him, sacrificed two bearded rams.

Conditions of the sacrifice:
Safety from faults.
(Four are indivisible in sacrificial sacrifices: the nakedness between its nakedness, and the sick man showing its disease, and the lame between its ribs and the unbelievable broken)
• The beginning of the time for slaughter immediately after the Eid prayer
The hadith) The Messenger of God, may God’s prayers and peace be upon him, said:
"Whoever is slaughtered before the prayer, but he is slaughtered for himself, and whoever is slaughtered after the prayer, his rituals are fulfilled, and the Sunnah of the Sunnah is struck.
• It is permissible for the victim to eat from his victim and to guide relatives and neighbors and give charity to the poor and needy
• Allah says :
 (فَكُلُوا مِنْهَا وَأَطْعِمُوا الْبَائِسَ الْفَقِيرَ) The Hajj: (28)
And whoever wants to sacrifice, let him hold his hair, nails and skin, meaning that he does not take anything from her when seeing the crescent of Dhu al-Hijjah until he sacrifices his sacrifice.
Hadith (on the authority of Umm Salamah): The Messenger of God, may God’s prayers and peace be upon him, said:
"When the tenth has entered, and one of you wants to sacrifice, then he will not touch his hair, nor his human beings." Narrated by Muslim.

Fadl Hadith:
It is not permissible for the one who wants to sacrifice taking from these three things - hair, nails and skin - until he sacrifices his sacrifice.
And Imam Ahmad went, and it is obligatory to abstain from these matters
And the audience went: to hate only
The first view is that it is more likely with evidence that the Messenger has forbidden that and the basic principle is that it is forbidden
• The person who wants to sacrifice is the one who must abstain, but if he shares his household with him, they do not have to abstain.
• Likewise, if someone else sacrifices it, the agent does not have to refrain from taking these things because he is a proxy, but the person who is and who is the one who must refrain.
• And whoever wants to sacrifice to comb and touch the good, but it is prevented from these three things.
• It is a common mistake that some sacrifice the dead and leave the living, knowing that they are more certain about the right of the living than the dead unless it is a will.

The virtue of Dhul Hijjah
On the authority of Ibn Abbas, may God be pleased with them, he said:
The Messenger of God, may God’s prayers and peace be upon him, said: “What good days of work there are more dear to God than these days - I mean the ten days - they said: O Messenger of God, and no jihad for the sake of God? He said: And there is no jihad for the sake of God, except for a man who came out with his own wealth and money and then did not return anything from it.
Ibn Hajar said:
Which shows that the reason for the concession of the tenth of Dhu al-Hijjah is the place where mothers of worship meet, which is prayer, fasting, charity and pilgrimage, and this does not come in other than
