Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 2
وَ سَأَلَ عَلِيُّ بْنُ جَعْفَرٍ أَخَاهُ مُوسَى بْنَ جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ عَنْ رَجُلٍ ذَبَحَ شَاةً فَاضْطَرَبَتْ فَوَقَعَتْ فِي بِئْرِ مَاءٍ وَ أَوْدَاجُهَا تَشْخُبُ دَماً هَلْ يُتَوَضَّأُ مِنْ تِلْكَ اَلْبِئْرِ قَالَ «يُنْزَحُ مِنْهَا مَا بَيْنَ ثَلاَثِينَ دَلْواً إِلَى أَرْبَعِينَ دَلْواً ثُمَّ يَتَوَضَّأُ مِنْهَا.
Ali ibn Ja'far asked his brother Imam Musa ibn Jafar Al-Kadhim عليه السلام about a man who slaughtered a sheep, which then convulsed and fell into a well while its veins were still bleeding. He asked if one could perform ablution from that well. Imam عليه السلام said: "Between thirty and forty buckets should be drawn from it, and then it may be used for ablution."
