Tradition

Ibne Hafs al-Marwazi reports from Imam Moosa b. Jafar (a.s.): Allah will grant the reward of seventy accepted pilgrimages to the Kaaba to anyone who goes on pilgrimage to the shrine of my son Ali (Al-Reza (a.s.)). He (a.s.) was asked – Do you mean the reward of seventy accepted pilgrimages to the Kaaba? The Imam (a.s.) replied – Yes, even more. The reward of seventy thousand pilgrimages to the Kaaba! He (a.s.) was asked – Do you mean the reward of seventy-thousand pilgrimages to the Kaaba? Imam (a.s.) replied: Yes. There are many occasions on which one’s pilgrimage to the Kaaba may not be accepted. When someone goes on pilgrimage to him (Imam Reza) or spends one night next to him, it is as if he has gone on the pilgrimage to Allah, the Highest at His Throne. The Imam (a.s.) was asked – Is the reward similar to going on the pilgrimage to Allah at His Throne? The Imam (a.s.) replied – Yes. When the Resurrection Day comes, there will be four of the previous and four of the latest divine leaders present at the Throne of the Sublime God. Those of the previous divine leaders will be Nuh (a.s.), Ibrahim (a.s.), Moosa (a.s.) and Esa (a.s.). And those of the latest divine leaders will be Muhammad (s.a.w.a.) Ali (a.s.) Hasan (a.s.) and Husain (a.s.). Then a rope will be dropped from the base of the Throne, and those who have gone on pilgrimage to the shrines of the Immaculate Imams (a.s.) will sit there along with us. Indeed those who have gone on pilgrimage to the shrine of my son Ali (Al-Reza (a.s.)) will have the highest rank there and will receive the greatest rewards.
