Imam Ali (AS) said, The people who work in this world are of two types: one works in this world for this world; his world has indeed distracted him from his Hereafter. He fears poverty for those whom he will leave behind but feels safe from it himself; so he spends his entire life for the benefit of others. The other one works in this world for that which is to come after it, so that which is [allotted] for him comes to him without [extra] work. Thus he acquires both the shares together and gains possession of both the abodes collectively.
