What Is Equivalent To A Cow For Sacrifice
أَخْبَرَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، عَنْ يَحْيَى، عَنْ عَبْدِ الْمَلِكِ، عَنْ عَطَاءٍ، عَنْ جَابِرٍ، قَالَ كُنَّا نَتَمَتَّعُ مَعَ النَّبِيِّ صلى الله عليه وسلم فَنَذْبَحُ الْبَقَرَةَ عَنْ سَبْعَةٍ وَنَشْتَرِكُ فِيهَا .
It was narrated that Jabir said: "We would make Tamattu' when the Prophet (ﷺ) was with us, and we would sacrifice a cow on behalf of seven people, sharing it among ourselves." (Sahih )
