Imam Ali (a.s.) points to a truth worth sitting with: on the day of judgement, the greatest regret will be felt by the man who earned wealth through sinful ways, although it is inherited by a person who spends it in obeying allah, the glorified one, and he will be awarded paradise on that account while the first one will be dragged into the fire on its account.

Tonight, account for one action before Allah does.
