It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that he heard the Prophet (peace and blessings be upon him) say: "The feet of one who gives false testimony will not even move from their place (on the Day of Resurrection) before Allah Almighty makes the Fire obligatory for him." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
