The scholar, commentator and scholar of Qur'anic science considered the Shiites' happiness in Ahl al-Bayt's happiness and added: it has been mentioned in the narrations that " the Shiites become happy by our happiness" because they are from us, they rejoice at what we are happy about. The Infallible Imams (as) and Ahlulbayt (as) rejoice at God's mercy, his forgiveness, his satisfaction, and his paradise. Our Shiites have the same happiness as we do, they are happy to receive God's mercy, forgiveness, and Paradise. Furthermore, they are not happy because they have a huge house or a brand-new expensive car. Our Shiites are not happy with such materialistic, far-flung and unreachable things. According to the Commander of the faithful, Imam Ali (as), the house we have is like a mosque in which we have to pray, have pure and good children and rest for our other positive works, the Shiites are of the same opinion. Our Shiites never get arrogant and brag about what they have in this world. They believe, those who have passed away also had these things, but they were buried all alone. Such things are not valuable to be happy about. We must see what makes Ahlulbayt (as) happy.
