أَخْبَرَنِي مُحَمَّدُ بْنُ آدَمَ، عَنْ عَبْدِ الرَّحِيمِ، - وَهُوَ ابْنُ سُلَيْمَانَ - عَنْ زَكَرِيَّا بْنِ أَبِي زَائِدَةَ، عَنْ أَبِي إِسْحَاقَ، عَنْ شُرَيْحِ بْنِ النُّعْمَانِ، عَنْ عَلِيٍّ، رضى الله عنه قَالَ أَمَرَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ نَسْتَشْرِفَ الْعَيْنَ وَالأُذُنَ وَأَنْ لاَ نُضَحِّيَ بِمُقَابَلَةٍ وَلاَ مُدَابَرَةٍ وَلاَ بَتْرَاءَ وَلاَ خَرْقَاءَ ‏.‏
