أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنْ الْحَسَنِ بْنِ رِبَاطٍ عَنْ أَبِي عَبْدِ اللهِ عَلَيْهِ السَّلَامُ قَالَ: سَأَلْتُهُ عَنِ الْبَالُوعَةِ تَكُونُ فَوْقَ الْبِئْرِ؟ قَالَ: إِذَا كَانَتْ أَسْفَلَ مِنَ الْبِئْرِ فَخَمْسَةُ أَذْرُعٍ، وَإِذَا كَانَتْ فَوْقَ الْبِئْرِ فَسَبْعَةُ أَذْرُعٍ مِنْ كُلِّ نَاحِيَةٍ، وَذٰلِكَ كَثِيرٌ.
Ahmad ibn Muhammad, from Muhammad ibn Sinan, from Al-Hasan ibn Ribbat, narrated from Abu Abdullah عليه السلام:
I asked Imam عليه السلام about a drain that is located above a well. Imam عليه السلام said: "If it is lower than the well, then the distance should be five cubits. If it is above the well, then the distance should be seven cubits from every direction. And that is sufficient."
