After the demise of Ayatullah Borujerdi, for which the Qum Theological School closed down for forty days mourning, on the first day that lessons began, the Imam in a speech at the Grand Mosque counseled the clergymen stating: "Never be worried for your sustenance." The clergymen asked that what they needed to do since the passing away of Ayatullah Borujerdi to which the Imam replied: "You must have such a lofty spiritual aspiration that the world should not be worth a straw for you."[1]
