Mukhtasar Bukhari

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."
