Sin of lying about the Prophet
Narrated by Sayyiduna Abu Huraira (may Allah be pleased with him) from the Noble Prophet (peace and blessings be upon him) that he (peace be upon him) said: "Keep my name, but do not keep my kunyah (my title, which is Abu al-Qasim) during my lifetime. And (be certain that) whoever sees me in a dream has indeed seen me, because Satan cannot assume my form, cannot take my appearance. And whoever deliberately lies about me should find his place in the Fire."
