وَ رَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ عَلِيِّ بْنِ رِئَابٍ عَنْ زُرَارَةَ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَنِ اَلْإِنْفَحَةِ تَخْرُجُ مِنَ اَلْجَدْيِ اَلْمَيِّتِ قَالَ "لاَ بَأْسَ بِهِ" قُلْتُ اَللَّبَنُ يَكُونُ فِي ضَرْعِ اَلشَّاةِ وَ قَدْ مَاتَتْ قَالَ "لاَ بَأْسَ بِهِ" قُلْتُ فَالصُّوفُ وَ اَلشَّعْرُ وَ عِظَامُ اَلْفِيلِ وَ اَلْبَيْضَةُ تُخْرَجُ مِنَ اَلدَّجَاجَةِ فَقَالَ "كُلُّ هَذَا ذَكِيٌّ لاَ بَأْسَ بِهِ".
Al-Hasan ibn Mahbub narrated from Ali ibn Ri'ab, from Zurara, who said: I asked Abu Abdullah (a.s), about the rennet (infaha) that comes out of a dead kid (young goat). Imam (a.s) said: "There is no harm in it." I asked about the milk that is in the udder of a sheep that has died. Imam (a.s) said: "There is no harm in it." I asked about wool, hair, elephant bones, and an egg that is taken from a hen. Imam (a.s) said: "All of these are pure and lawful; there is no harm in them."
