The words of the [infallible Shia] Imams and the scholars about Imām Mahdī
I asked ‘Allāmah Tabataba’i if it is possible to visit His Excellency [Sāhib al- Zamān (mgehr)] or no?! He returned, ‘Yes, but on three conditions: Being completely pious, feeling a great love [to the Imām (mGehr)], and being persistent in reciting Zīyāra Āl Yāsīn (the long version).’ (Gham-e Eshgh, P. 90)
