3ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ وَمُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ جَمِيعاً عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَفْصِ بْنِ الْبَخْتَرِيِّ عَنْ مَنْصُورِ بْنِ حَازِمٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ عَلَى الْمُتَمَتِّعِ بِالْعُمْرَةِ إِلَى الْحَجِّ ثَلاثَةُ أَطْوَافٍ بِالْبَيْتِ وَيُصَلِّي لِكُلِّ طَوَافٍ رَكْعَتَيْنِ وَسَعْيَانِ بَيْنَ الصَّفَا وَالْمَرْوَةِ.
