The Messenger of Allah (saw) mentioned all the sins that will lead one to Hell. Muslim reports from 'Iyadh bin Himaar that the Messenger of Allah (saw) said, during a lengthy khutbah:
"..the people of Hell are five: the weak who lack the power to (avoid evil); the (carefree) who pursue (everything irrespective of whether it is good or evil) and who have no concern for their families or their wealth; the dishonest people whose greed cannot be concealed even in the case of minor things; and those who betray you, morning and evening, with regard to your family and your property. He also mentioned misers, liars and those who are in the habit of abusing people and using obscene, foul language". (Muslim in Kitaab al-Jannah wa Sifaat Na'imihaa Baab as-Sifaat allaatee yu'raf bihaa fid-dunyaa ahl al-Jannah wa ahl an-Naar, 4/2197 no. 2865)
