* 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.
