The Importance of Imam Sadiq (as) advices to Unwan e basari Ayatollah Tahrir: Imam Sadiq (as) advices to Unwan e basari are so important that great mystics like Ayatollah Sayyid Ali Qazi (may Allah have mercy on him) used to instruct his disciples, followers and those who were thirsty for guidance to write the hadith and always keep it with them and read it once or twice a week and follow its instructions. In addition to the abundance of teachings in this tradition, there is also deep material in terms of Imam Sadiq’s (as) school of thought regarding mentoring of souls.
