عَنْ عَبْدِ السَّلَامِ بْنِ صَالِحٍ الْهَرَوِيِّ قَالَ: سَمِعْتُ اَبَا الْحَسَنِ عَلِيَّ بْنَ مُوسَى الرِّضَا ع يَقُولُ رَحِمَ اللهُ عَبْدًا اَحْيَا اَمْرَنَا فَقُلْتُ لَهُ وَ كَيْفَ يُحْيِي اَمْرَكُمْ قَالَ يَتَعَلَّمُ عُلُومَنَا وَ يُعَلِّمُهَا النَّاسَ فَاِنَّ النَّاسَ لَوْ عَلِمُوا مَحَاسِنَ كَلَامِنَا لَاتَّبَعُونَا
Abd al-Salaam Ibn Saaleh al-Harawiyy said: I heard Imam Reza (peace be upon him) say, “May Allah have mercy on the person who enlivens our affair (i.e. Wilayat)!” I asked, “How is your affair enlivened?” He (peace be upon him) informed,
“He learns our knowledge (traditions) and teaches it to the people. Surely, if people knew the beauty of our words, they would certainly follow us.”
