Sunan Ibn Majah, Book 26, Hadith 3261 (In-Book) ⓘ
It was narrated from Jabir that the Messenger of Allah said: ‘Do not slaughter anything but a Musinnah,* unless there is none available, in which case you can slaughter a Jadha’a among sheep.”
حَدَّثَنَا هَارُونُ بْنُ حَيَّانَ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ عَبْدِ اللَّهِ، أَنْبَأَنَا زُهَيْرٌ، عَنْ أَبِي الزُّبَيْرِ، عَنْ جَابِرٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " لاَ تَذْبَحُوا إِلاَّ مُسِنَّةً إِلاَّ أَنْ يَعْسُرَ عَلَيْكُمْ فَتَذْبَحُوا جَذَعَةً مِنَ الضَّأْنِ " .
