[Machine] Abu Ubaid Al-Fur'ul is a descendant of the "Dabua" (a type of wild wolf) among the Arabs. The meaning of this saying is that he compared a female sheep to a sheep, saying that it is permissible (halal) just like the sheep.
أَبُو عُبَيْدٍ الْفُرْعُلُ عِنْدَ الْعَرَبِ وَلَدُ الضَّبُعِ وَالَّذِي يُرَادُ مِنْ هَذَا الْحَدِيثِ قَوْلُهُ نَعْجَةٌ مِنَ الْغَنَمِ يَقُولُ إِنَّهَا حَلَالٌ بِمَنْزِلَةِ الْغَنَمِ
