Abu Qatadah ibne-Rib i Radiyallahu anhu reported
that Rasulullah Sallallahu alaihi wasallam narrates
in a Hadith Qudsi that Allah Azza wa Jall has said:
Verily, I have enjoined upon your Ummah five time Salat,
and I have taken upon myself an oath that anyone
who observes them at their appointed time,
I shall admit him into Paradise;
if anyone does not offer them regularly,
there is no such guarantee from Me for him.
( I may punish him or forgive him )
{ Abu Dawud }
