Qurban is prescribed and recommended. It includes muakkadah or mandatory sunnah. Among the differences of the scholars'.
One goat is accepted for a person and his family even though there are many (family members). As narrated by Tirmizi, (1505) and Ibn Majah, (3147) from Atho 'bin Yasar said:
سألت أبا أيوب الأنصاري كيف كانت الضحايا على عهد رسول الله صلى الله عليه وسلم فقال: "كان الرجل يضحي بالشاة عنه وعن أهل بيته فيأكلون ويطعمون حتى تباهى الناس فصارت كما ترى).
"I asked Abu Ayyub Al-Anshory, how was the condition of the qurban at the time of the Prophet sallallahu'alaihi wa sallam, so he said," In the past someone sacrificed with one goat for himself and his family. They eat and feed. Until people are racing up to what you can see. "
Nawawi rahimahullah said, "One goat is accepted for one person and not more than one person is accepted. However, if a family member makes a sacrifice, then he has carried out the message for all (his family). So that the sacrifice for him is included in the Sunnah of the kifayah (which is sufficient). Completed from 'Al-Majmu', (8/370).
If he slaughtered more than one, it was fine while not because he wanted to show off.
Shaykh Ibn Baz rahimahullah was asked, "Does Islam specify the number (animal) for qurban, where a Muslim sacrifices on the Eid al-Adha? And what are the numbers if there are numbers?
He replied, "There is no number stipulation. In the past the Prophet sallallahu'alaihi wa sallam sacrificed with two (goats) one of them for him and his family and the second for the people of Muhammad sallallahu'alaihi wa sallam who obeyed Allah. If a person sacrifices one, two or more of these, that is fine. Abu Ayyub Al-Anshori radhiallahu'anhu said, “In the past we sacrificed at the time of the Prophet sallallahu'alaihi wa sallam with one goat, we ate and we fed. Then people show off after that. In conclusion, one (goat) is sufficient if a person sacrifices for his family with one goat for himself and his family. He has earned the sunnah by doing that. If you sacrifice two, three or a camel or a cow, that's okay. " Finish from Sheikh Bin Baz's website:
What is more important is that one goat is enough for himself and for his family. Because this is the guidance of the Prophet sallallahu'alaihi wa sallam.
عن جابر بن عبد الله قال شهدت مع رسول الله صلى الله عليه وسلم الأضحى بالمصلى فلما قضى خطبته نزل من منبره وأتي بكبش فذبحه رسول الله صلى الله عليه وسلم بيده وقال بسم الله والله أكبر هذا عني وعمن لم يضح من أمتي) رواه أبو داود (2810 ) وصححه الشيخ الألباني في صحيح أبي داود.
From Jabir bin Abuddllah said, I witnessed with the Prophet sallallahu'alaihi wa sallam qurbani in the mushollah (place of prayer). When he finished giving the sermon, he got down from the pulpit. The sheep were brought in and the Prophet sallallahu'alaihi wa sallam slaughtered them with his hands. By saying,
بِسْمِ اللَّهِ وَاللَّهُ أَكْبَرُ هَذَا عَنِّي وَعَمَّنْ لَمْ يُضَحِّ مِنْ أُمَّتِي (In the name of Allah and Allah is Great, this is for me and for my people who have not yet sacrificed).
Hr. Abu Dawud, (2810) declared shoheh by Sheikh Al-Albany at Shoheh Abi Dawud.
Shaykh Ibn Uthaimin rahimahullah said, "There is no doubt, that sticking to the sunnah is better than not. If we say, “It is in accordance with the sunnah that the householder is sufficient to make a sacrifice with one that is done by the head of the family. Not that if he slaughtered more than one they were sinners. They are innocent. However, keeping the sunnah is better than many practices. Allah subhanahu wata'ala said, "He (Allah) tests all of you, who is the best at his practice. SQ. Al-Mulk: 2.
Therefore, when the Prophet sallallahu'alaihi wa sallam sent two people in a need and both of them did not get water, so both of them prayed and prayed. Then after that get water. One of them performs ablution 'and repeats the prayer. While others do not perform ablution and do not repeat prayers. Then it was told to the Prophet sallallahu'alaihi wa sallam. He said to those who do not repeat (ablution and prayer), “You are according to the sunnah. And said to the second one, “You are rewarded twice. Which of the two is better? That is in accordance with the sunnah, even though the other one gets two rewards. He got two rewards, because he had done two practices with the intention of getting closer to Allah Azza wajalla. So that he gets two rewards, but not like those who do according to the sunnah. " Finish from Fatawa Nurun 'Alad Darbi.
Allah knows best.
