عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ عُمَرَ بْنِ أُذَيْنَةَ عَنْ زُرَارَةَ عَنْ أَبِي جَعْفَرٍ ( عليه السلام )
قَالَ إِذَا وَقَعَتِ الْفَأْرَةُ فِي السَّمْنِ فَمَاتَتْ فِيهِ فَإِنْ كَانَ جَامِداً فَأَلْقِهَا وَ مَا يَلِيهَا وَ كُلْ مَا بَقِيَ وَ إِنْ كَانَ ذَائِباً فَلَا تَأْكُلْهُ وَ اسْتَصْبِحْ بِهِ وَ الزَّيْتُ مِثْلُ ذَلِكَ .
1. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Umar ibn ‘Udhaynah from Zurarah who has said the following: “Abu Ja‘far 
, has stated this Hadith.
‘If a rat falls in ghee and dies in it, if it is solid, it (the rat) then must be thrown away as well as whatever has come in contact with it. If it is fluid you must not use it for food but you can use it for lighting during the night and so also is the case about oil.”’
