Who said, who reported the Hadith that says "One who said lie about Prophet (Sallallahu Alaihi wa Sallam), let him find his place in Hell" ? Please send me a complete answer.

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

The Hadith you mentioned is a sound one reported by Al-Bukhari and Muslim . Al-Bukhari reported it from Al-Mughaira Ibn Shuba and Muslim reported it from Abu Hurairah . The words of the Hadith as it is in Sahih Al-Bukhari are: "Attributing falsehood to me is not just like attributing falsehood to anyone else. Whoever deliberately attributes any falsehood to me he should, in fact, find his abode in the Hell-Fire."
Allah knows best.
