٤۔٧١ باب مَا يَقَعُ مِنَ النَّجَاسَاتِ فِي السَّمْنِ وَالْمَاءِ
[Machine] "And Al-Zuhri said, 'There is no harm in water as long as its taste, smell, or color has not been changed.' And Hammad said, 'There is no harm in using the feathers of a dead animal.' And Al-Zuhri said, 'I have seen people from the past scholars using bones of the deceased such as the elephant and others for combing their hair and applying oil on it, without seeing any harm in it.' And Ibn Sireen and Ibrahim said, 'There is no harm in trading ivory.'"
وَقَالَ الزُّهْرِيُّ لاَ بَأْسَ بِالْمَاءِ مَا لَمْ يُغَيِّرْهُ طَعْمٌ أَوْ رِيحٌ أَوْ لَوْنٌ. وَقَالَ حَمَّادٌ لاَ بَأْسَ بِرِيشِ الْمَيْتَةِ. وَقَالَ الزُّهْرِيُّ فِي عِظَامِ الْمَوْتَى نَحْوَ الْفِيلِ وَغَيْرِهِ أَدْرَكْتُ نَاسًا مِنْ سَلَفِ الْعُلَمَاءِ يَمْتَشِطُونَ بِهَا، وَيَدَّهِنُونَ فِيهَا، لاَ يَرَوْنَ بِهِ بَأْسًا. وَقَالَ ابْنُ سِيرِينَ وَإِبْرَاهِيمُ وَلاَ بَأْسَ بِتِجَارَةِ الْعَاجِ.
