حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ ، حَدَّثَنَا زُهَيْرٌ ، حَدَّثَنَا أَبُو الزُّبَيْرِ ، عَنْ جَابِرٍ ، قَالَ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " لَا تَذْبَحُوا إِلَّا مُسِنَّةً إِلَّا أَنْ يَعْسُرَ عَلَيْكُمْ فَتَذْبَحُوا جَذَعَةً مِنَ الضَّأْنِ " .
Jabir reported Allah's Messenger (ﷺ) as saying: Sacrifice only a grown-up animal, unless it is difficult for you, in which case sacrifice a ram (of even less than a year, but more than six months' age).
