Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Do you know what thing will cause people to enter the Fire the most?" The people said: Allah and His Messenger know best. He (peace be upon him) said: "The two hollow things: the private parts and the mouth. And what will cause people to enter Paradise the most is the fear of Allah and good character."
