3870 - وَ رُوِيَ عَنْ مُحَمَّدِ بْنِ عَلِيِّ بْنِ مَحْبُوبٍ قَالَ : كَتَبَ رَجُلٌ إِلَى اَلْفَقِيهِ عَلَيْهِ اَلسَّلاَمُ فِي رَجُلٍ كَانَتْ لَهُ رَحًى عَلَى نَهَرِ قَرْيَةٍ وَ اَلْقَرْيَةُ لِرَجُلٍ أَوْ لِرَجُلَيْنِ فَأَرَادَ صَاحِبُ اَلْقَرْيَةِ أَنْ يَسُوقَ اَلْمَاءَ إِلَى قَرْيَتِهِ فِي غَيْرِ هَذَا اَلنَّهَرِ اَلَّذِي عَلَيْهِ هَذِهِ اَلرَّحَى وَ يُعَطِّلَ هَذِهِ اَلرَّحَى أَ لَهُ ذَلِكَ أَمْ لاَ فَوَقَّعَ عَلَيْهِ اَلسَّلاَمُ "يَتَّقِي اَللَّهَ وَ يَعْمَلُ فِي ذَلِكَ بِالْمَعْرُوفِ وَ لاَ يُضَارُّ أَخَاهُ اَلْمُؤْمِنَ " وَ فِي رَجُلٍ كَانَتْ لَهُ قَنَاةٌ فِي قَرْيَةٍ فَأَرَادَ رَجُلٌ آخَرُ أَنْ يَحْفِرَ قَنَاةً أُخْرَى فَوْقَهَا فَمَا يَكُونُ بَيْنَهُمَا فِي اَلْبُعْدِ حَتَّى لاَ يُضِرَّ بِالْأُخْرَى فِي أَرْضٍ إِذَا كَانَتْ صَعْبَةً أَوْ رِخْوَةً فَوَقَّعَ عَلَيْهِ اَلسَّلاَمُ "عَلَى حَسَبِ أَنْ لاَ يُضِرَّ أَحَدُهُمَا بِالْآخَرِ إِنْ شَاءَ اَللَّهُ تَعَالَى".
Hadith.3870 - It is narrated from Muhammad bin Ali bin Mahbub who said: A man wrote to the 'Jurist' (Imam Hasan ibn Ali Al-Askari 
) regarding a case where a man had a mill situated on a river that passed through a village. The village belonged to one or two men. The owner of the village wanted to divert the water to his village through a different channel, which would disable the mill. He asked whether he had the right to do so.
The 'Jurist' Imam responded: "He should fear Allah (swt) and act in a fair manner, and he should not harm his believing brother."
He also asked about a man who had a canal in a village, and another man wanted to dig another canal above it. He inquired about the required distance between them so that one would not harm the other, especially if the land was either hard or soft.
The 'Jurist' Imam responded: "It should be done in such a way that neither of them harms the other, if Allah (swt) wills."
