While Shafa'ee mazhab allows to pray "Janaza without the dead infornt" Ghaib Janazah Salah based on the below Ahadees.
Narrated Abu Huraira (RA) Allah's Apostle (Sallaho Alaihe Wassallam) informed (the people) about the death of An-Najashi on the very day he died. He went towards the Musalla (praying place) and the people stood behind him in rows. He said four Takbirs (i.e. offered the Funeral prayer). [Bukhari]
However, I heard a few scholars from Hanafi Mazhab says that the body of Najashi did appear in front of the prophet s.a.w. while praying ghaib janazah salah.
Any references / evidances or explanation around this anyone could share please ?
