Abdullah ibne-Qurt Radiyallahu anhu narrates
that Rasulullah Sallallahu alaihi wasallam said:
On the Day of Judgement, the first thing that
a slave of Allah will be held accountable for is Salat.
If it is found sound and satisfactory,
the rest of his deeds
will aslo be sound and satisfactory,
and if found corrupt and rotten, then the rest
of his deeds will also be corrupt and rotten.
(Tabarani, Targhib)
