The Ahlulbayt are the pure lights and are concerned about the Shiites' hereafter. The Shiites who are the subcategory of the Ahlulbayt (peace be upon them) and the light of Allah are concerned and worried about the hereafter. The one who has no worries about hereafter are the people who usurp and are guilty of bribery, corruption, embezzlement and other great sins, but Ahlulbayt and their followers are worried about their hereafter. In return, Allah Almighty considers their best deed as a scale while granting them rewards and opens all the doors of mercy for them and bless them all without taking hard on them.
