3ـ الْحُسَيْنُ بْنُ مُحَمَّدٍ عَنْ مُعَلَّى بْنِ مُحَمَّدٍ عَنِ الْحَسَنِ بْنِ عَلِيٍّ عَنْ أَبَانٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عَبْدِ الله وَفُضَيْلٍ وَمُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) أَنَّهُ سُئِلَ عَنِ الطِّيبِ عِنْدَ الإِحْرَامِ وَالدُّهْنِ فَقَالَ كَانَ عَلِيٌّ صَلَوَاتُ الله عَلَيْهِ لا يَزِيدُ عَلَى السَّلِيخَةِ.
