It means that when we intend to take a step, we should ponder upon it whether Imam az-Zaman (aj) shall be pleased with it or not. We should do it only if it is as per his wishes and not if it is going to earn his displeasure. In such situations we should overcome our personal desires and achieve the Imam’s pleasure. You shall become his loved one and remembered in good words by Imam (aj) and his forefathers.
This is mentioned in the tradition recorded by Fazil Muhaddith Noori quoting from Amali of Shaykh Tusi that the narrator1 asked Imam Sadiq (as), “Why do we hear so much about Salman the Persian from you?” Imam (as) said, “Do not call him Salman the Persian, say Salman the Muhammadan. Do you know why I remember him so much.” “I don’t know,” said the narrator. “It is due to three things”, said the Imam (as), “He gave preference to the desire of Amirul Momineen (as) over his personal wishes. Befriending the poor and preferring them over affluent people and his attachment to knowledge and scholars. Indeed Salman was a righteous Muslim and not of the polytheists.”2
I say: Ponder upon these qualities and all the good things that are related to him and know that the Imam himself has these traits and he likes these qualities and has praised them. So please put these traditions into practice and gain the good of the world and the hereafter. May the Almighty Allah give me and all believers the Taufeeq to act on these things; He is the proximate One and the One Who answers the supplications.
