البيهقي:١١٠١أَخْبَرَنَا أَبُو بَكْرِ بْنُ الْحَارِثِ الْفَقِيهُ أنا عَلِيُّ بْنُ عُمَرَ الْحَافِظُ أنبأ الْحُسَيْنُ بْنُ إِسْمَاعِيلَ ثنا مُحَمَّدُ بْنُ شَاذَانَ حَدَّثَنِي مُعَلَّى ثنا شَرِيكٌ عَنْ أَبِي إِسْحَاقَ عَنِ الْحَارِثِ عَنْ عَلِيٍّ قَالَ

إِذَا أَجْنَبَ الرَّجُلُ فِي السَّفَرِ تَلَوَّمَ مَا بَيْنَهُ وَبَيْنَ آخِرِ الْوَقْتِ فَإِنْ لَمْ يَجِدِ الْمَاءَ تَيَمَّمَ وَصَلَّى الْحَارِثُ الْأَعْوَرُ لَا يُحْتَجُّ بِهِ
