أبو داود:٣٠٧٨حَدَّثَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ أَخْبَرَنَا ابْنُ وَهْبٍ أَخْبَرَنِي مَالِكٌ قَالَ هِشَامٌ الْعِرْقُ الظَّالِمُ

أَنْ يَغْرِسَ الرَّجُلُ فِي أَرْضِ غَيْرِهِ فَيَسْتَحِقَّهَا بِذَلِكَ قَالَ مَالِكٌ وَالْعِرْقُ الظَّالِمُ كُلُّ مَا أُخِذَ وَاحْتُفِرَ وَغُرِسَ بِغَيْرِ حَقٍّ
