One might say that:” one can easily go to paradise by doing the obligatory deeds (Wajebat) and avoiding the prohibited deeds (Moharramat)”, in response we must say:” the paradise has seven floors, Allah Almighty will place the one who has done obligatory deeds (Wajebat) and avoided the prohibited deeds in the first floors of the paradise, but the one who has added weeping for Imam Hussein peace be upon him to his good deeds will have the palaces and top floors of the paradise.
The palaces and top floors of the paradise are the place where the divine prophets are present there, in other words, the weepers positions are the same as the positions of the divine prophets.
