Chapter 139 | The Rare Ahadith about Tawaf
17ـ أَحْمَدُ بْنُ مُحَمَّدٍ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ بَعْضِ أَصْحَابِهِ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَم) قَالَ طَوَافٌ فِي الْعَشْرِ أَفْضَلُ مِنْ سَبْعِينَ طَوَافاً فِي الْحَجِّ.
17. Ahmad ibn Muhammad has narrated from Ibn Abi ‘Umayr from certain persons of his people who has said the following: “Abu ‘Abd Allah , has said, ‘Performing a Tawaf on tenth of Dhu al-Hajjah is more virtuous than seventy Tawaf during al-Hajj.’”
