What is the status of a person who rejects all Hadith?

Answer

He is a moron murtad. The one who rejects Hadith is not a Muslim. Ask him:

 Where in the Qur'aan is it mentioned that there are five Fardh Salaat?

 Where are all the Fardh and Sunnat raka'ts mentioned in the Qur'aan?

 Where in the Qur'aan are the details of Zakaat mentioned?

 Where in the Qur'aan are all the rites of Hajj mentioned?

 Where in the Qur'aan is it mentioned that the dead should be buried and not cremated?

 Where in the Qur'aan is it mentioned about the Ghusl, Kafan, etc. for the mayyit?

 Where in the Qur'aan are the thousands of Deeni masaa-il mentioned.

Then to clinch the argument ask the jaahil:

On what basis does he believe that the Qur'aan that he and we are reciting was revealed to Rasulullah (Sallallahu alayhi wasallam) from Allah Ta'ala? On what basis has the order of the Surahs been compiled? Who says that this Book is the revealed Qur'aan of Allah Ta'ala? Who told him that this Book is a revelation from Allah Ta'ala? Did Jibraeel come to him to inform him of this fact? Brother, this chap is a human shaitaan. It is best to stay very far from him.
