And on the Day when the Hour will be established -- that Day shall (all men) be separated.Qatadah said:"By Allah, this refers to the separation after which there will be no reunion."In other words, if one person is taken up to the highest heights and another is sent down to the lowest depths of Hell, that is the last they will ever see of one another.Allah says:فَأَمَّا الَّذِينَ امَنُوا وَعَمِلُوا الصَّالِحَاتِ فَهُمْ فِي رَوْضَةٍ يُحْبَرُونَ
