And by this isnad. Al-Sadiq (as) saw a man intensely mourning his son, so he said
O you! You have mourned over the minor calamity, but you have been heedless of the major calamity. Had you prepared yourself for what would happen to your son, your mourning would not have been as intense. Your calamity of abandoning preparedness for this is greater than your calamity over your son.
