Another responsibility of the believers is that when they hear or see the name of Imam al-Zaman or any of his titles, they should immediately show the appropriate form of respect. In addition, as a sign of acknowledging his status, they should stand up when they hear his blessed title, al-Qa`im.
One day, a person was in a gathering with Imam Ja’far b. Muhammad as-Sadiq (as) when another person took the name of Imam al-Zaman (ajtf) and out of respect to the 12th Imam, the 6th Imam stood up!1
Once, a companion named Di’bil, who lived in the later part of the Islamic history, recited a poem which he had composed in which he mentioned Imam al-Hujjah (ajtf) to the 8th Imam, ‘Ali b. Musa al-Rida (as). When he mentioned the 12th Imam, Imam al-Rida (as) stood up and placed his right hand on his head as a form of respect to the final Imam and prayed for his speedy arrival!2
The philosophy behind standing up when one hears the blessed name or title of the Imam, especially al-Qa`im (ajtf) is that we are showing our readiness to rise to help and assist the Imam.
Indeed, whenever and wherever the name of the Imam is taken, he immediately makes himself present in that gathering and looks with attention towards the people (who have taken his name) and therefore, it is recommended to show respect to the Imam by standing up whenever his name is mentioned.
