Malik related to me from Amr ibn Yahya al-Mazini that his father said, "There was a stream in my grand-father's garden belonging to Abd ar-Rahman ibn Awf Abd ar-Rahman ibn Awf wanted to transfer it to a corner of the garden nearer to his land, and the owner of the garden prevented him. Abd ar-Rahman ibn Awf spoke to Umar ibn al-Khattab about it, and he gave a judgement to Abd ar-Rahman ibn Awf that he should transfer it."  

أَنَّهُ قَالَ كَانَ فِي حَائِطِ جَدِّهِ رَبِيعٌ لِعَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ فَأَرَادَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ أَنْ يُحَوِّلَهُ إِلَى نَاحِيَةٍ مِنَ الْحَائِطِ هِيَ أَقْرَبُ إِلَى أَرْضِهِ فَمَنَعَهُ صَاحِبُ الْحَائِطِ فَكَلَّمَ عَبْدُ الرَّحْمَنِ بْنُ عَوْفٍ عُمَرَ بْنَ الْخَطَّابِ فِي ذَلِكَ فَقَضَى لِعَبْدِ الرَّحْمَنِ بْنِ عَوْفٍ بِتَحْوِيلِهِ
