4ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ تُكْرَهُ الصَّلاَةُ فِي الْفِرَاءِ إِلاَّ مَا صُنِعَ فِي أَرْضِ الْحِجَازِ أَوْ مِمَّا عُلِمَتْ مِنْهُ ذَكَاةٌ.
4. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad from al-Halabiy who has said the following: “Abu ‘Abd Allah (a.s.), has said, ‘It is undesirable to perform Salah (prayer) in fur except those made in al-Hijaz or that you know is properly slaughtered.’”
