Hadith 1533
tawaf
3ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنِ ابْنِ فَضَّالٍ عَنِ ابْنِ الْقَدَّاحِ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ طَوَافٌ قَبْلَ الْحَجِّ أَفْضَلُ مِنْ سَبْعِينَ طَوَافٍ بَعْدَ الْحَجِّ.
3. A number of our people have narrated from Sahl ibn Ziyad from ibn Faddal from ibn al-Qaddah who has said the following: “Abu ‘Abd Allah (a.s.), has said that performing Tawaf before al-Hajj is more excellent than seventy Tawaf after al-Hajj.”
