Those who share in buying the Adhha sacrificial Animal should not remove any of their Hair
Question :
I am a widow and I have sons and a daughter and we all live in one house. Likewise, our wealth and our possessions are one (i.e., shared). We have not separated our possessions since the death of my husband. Every year we give the responsibility of buying an Adhha sacrificial animal for us to one of my sons and he slaughters it. So, who is the person who is required to abstain from removing anything from his hair and nails during the 10 days of Thul-Hijjah? Are we all required to refrain from this?
Answer:
If the matter is like what was mentioned in the question of the family sharing in wealth and the Adhha sacrifice, then all of you are considered as performing the Adhha sacrifice. It is not permissible for anyone of you to remove any of his hair or nails or anything from his skin after the entrance of the month of Thul-Hijjah until the Adhha animal is sacrificed. This is due to the statement of the Prophet :
"When the month of Thul-Hijjah enters and one of you wants to perform an Adhha sacrifice, he should not remove anything from his hair or his nails or his skin."
This was recorded by Imam Muslim in his Sahih from a Hadith of Umm Salamah. And success is from Allâh.
