Rasulullah (Sallallahu alayhi wasallam) said, "A person neglecting his salaah (even though he makes it up later) shall remain in Jahannam for a period of one Huqb. A Huqb is equal to eighty years of three hundred and sixty days each, and a day in the Hereafter shall equal one thousand years of this world.” Rasulullah (Sallallahu alayhi wasallam) also said, "The name of a person who neglects even a single fardh salaah intentionally is written on the gate of Jahannam, which he must enter." Once, Rasulullah (Sallallahu alayhi wasallam) said, "Please, O Allah! Let not anyone of us to be a miserable poor person." He then said: "Do you know who is a miserable poor person?" When the Sahaaba (RA) asked, he explained to them saying, "A wretched destitute is the one who neglects his salaah. In Islaam there is nothing for him." In another hadith it is said, "Allah Ta’ala will not care a bit for the person who has been neglecting salaah intentionally, and for him shall be a terrible fate."
