Hadith 8:2772
Abu Bakr narrated to us, he said: Kathir ibn Hisham narrated to us, from Ja'far, from Maymun, who said: Whoever makes a *badana* (a camel for sacrifice) incumbent upon himself, he shall not slaughter it except in Makkah. And whoever makes a *jazur* (a camel) incumbent upon himself, he may slaughter it wherever he wishes.
حدثنا أبو بكر قال نا كثير بن هشام عن جعفر عن ميمون قال من جعل عليه بدنة فإنه لا ينحرها إلا بمكة ومن جعل عليه جزورا نحرها حيث شاء
