1540. hadíth
وَ فِي خَبَرٍ آخَرَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: "كُلْ مَا أَكَلَ مِنْهُ اَلْكَلْبُ وَ إِنْ أَكَلَ مِنْهُ ثُلُثَيْهِ كُلْ مَا أَكَلَ اَلْكَلْبُ وَ إِنْ لَمْ يَبْقَ مِنْهُ إِلاَّ بَضْعَةٌ وَاحِدَةٌ".
And in another narration, Imam Jafar ibn Muhammad Al-Sadiq (a.s) said: "Eat whatever the dog has eaten from, even if it has eaten two-thirds of it. Eat whatever the dog has eaten, even if nothing remains of it except a single piece."
