Whoever slaughters his sacrificial Animal before the Day of 'Eid due to Ignorance
Question :
We assumed Ihram and we were a group performing Hajjut-Tamattu'. So, we performed 'Umrah and removed our Ihram. Then some of the people suggested that we should slaughter a sacrificial animal and distribute it in Makkah. Thus, the slaughter was done in Makkah. Then, after this we learned that the slaughter is not to be until after stoning the pillar of Al-'Aqabah. I knew that and I told them to delay the slaughter until the day of the Sacrifice or after it. However, they went ahead with the slaughter one day after we had arrived and performed 'Umrah. So, what is the ruling on that and what are we required to do in this situation?
Answer:
Whoever slaughtered the sacrifice of 'Umrah or At- Tamattu' before the Eid, that does not suffice him, because the Messenger ﷺ and his Companions did not slaughter until the days of Sacrifice. They came performing Hajjut-Tamattu on the 4th day of Thul-Hijjah and the sheep and camels that were with them remained pinned in their places until the day of Sacrifice came. If slaughtering them was permissible before that, the Prophet ﷺ and his Companions would have done it in a hurry during the four days that they stayed in Makkah before going out to Mina. This is because the people were in need of meat at that time. However, since the Prophet ﷺ did not slaughter, and neither did his Companions, until the day of Sacrifice came, that proves that it is not sufficient to do so before that. It also proves that the person who slaughters before the day of Sacrifice has opposed the Sunnah and come with a new legislation. Therefore, it is not acceptable, just like the person who prays or fasts before its time. The fast of Ramadhan is not correct before its time nor is the prayer that is offered before its time, and so forth.
Thus, the result is that this act of worship was performed before its time and therefore it does not suffice. The person must repeat this slaughter if he is able. If he is not able, he must fast 3 days during the Hajj and 7 days when he returns to his family (i.e., his homeland). Thus, it is 10 days all together which take the place of the slaughter.
