Fiqh of Corpses - Sutomo Abu Nashr.
Rasulullah SAW said, "An intelligent person is he who prepares himself by doing good deeds for life after death." From this Hadith, we are taught about who the person who is called intelligent really is. It turns out that in the view of this hadith, intelligent is not having a high IQ, full of academic achievements, being able to memorize various courses and subjects and so on. But an intelligent person is one who always carries out Allah SWT's commands and stays away from his prohibitions in preparation for death.
