One summer when the Imam was in Tehran, he participated in the congregations prayers led by Ayatullah Sayyid Abu'l-Hasan Rafi'i Qazvini. Mr. Rafi'i was leading the dusk and night mandatory prayers in the Friday Mosque of Tehran, but he would not come regularly. One day when Mr. Rafi'i came late, the Imam stood up and told the people who were participating in that congregation prayer that, "Come on and let us tell him to lead the prayers regularly. In this irregular manner that he comes, he wastes the time of many people. All of us together should tell him to hold the congregation prayers regularly."
After that Mr. Rafi'i came and began to hold the prayers. After the prayers were ended, a person told him that: "A young man was telling the people to tell you to be punctual. He was almost protesting your unpunctuality." Mr. Rafi'i responded saying: "Who was that man?" That man pointed to the Imam who was busy reciting prayers on the other side. As soon as Mr. Rafi'i's eyes fell on the Imam, he stated: "He is Haj Aqa Ruhullah. He is a man who is extremely learned, accomplished, extremely pious, disciplined and spiritually pure; he is right. If I come late again then request him to lead the prayers on my behalf.[1]
