What is the reference of this Hadith?
من صلى أربع ركعات قبل الظهر وأربعا بعدها حرمه الله عز وجل على النار
These words are recorded in Sunan Nasai on the authority of Sayyidah Ummu Habibah (radiyallahu ‘anha).
(Sunan Nasai; Al Mujtaba, Hadith: 1814)
Imam Tirmidhi (rahimahullah) has recorded the Hadith with very slight variation in the wording.
(Sunan Tirmidhi, Hadith: 427)
Whomsoever offers four rak’ahs before Zuhr and four rak’ahs after Zuhr, Allah ‘Azza wa Jalla will forbid him from the Fire [i.e. Allah will protect him from Jahannam].

And Allah Ta’ala Knows best.
