٩ حَدَّثَنِي جَمَاعَةُ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ إِدْرِيسَ وَ مُحَمَّدِ بْنِ يَحْيَى الْعَطَّارِ عَنِ الْعَمْرَكِيِّ بْنِ عَلِيٍّ عَنْ بَعْضِ أَصْحَابِهِ عَنْ بَعْضِهِمْ (ع) قَالَ أَرْبَعُ عُمَرٍ تَعْدِلُ حِجَّةً وَ زِيَارَةُ قَبْرِ الْحُسَيْنِ ع تَعْدِلُ عُمْرَةً
9. A group of our companions narrated to me from Aĥmad ibn Idrǐs, and from Muĥammad ibn Yaĥyā Al-‘Aťťār, from ‘Amraki ibn ‘Ali, from some of his companions, from one of them (the infallible Imams ), who said: Performing four ‘Umrah is equal to performing a Hajj, and going to the Ziyārah of the grave of Ĥusain  is equal to performing an ‘Umrah.
