عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ الْجَذَعُ مِنَ الضَّأْنِ خَيْرٌ مِنَ السَّيِّدِ مِنَ الْمَعْزِ قَالَ دَاوُدُ السَّيِّدُ الْجَلِيلُ
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him, said: A one-year-old sheep from the sheep breed is better than a mature goat from the goat breed. Dawud said: By "mature" is meant a large (good and healthy animal).
