Sayyiduna Abu Salma (RadhiAllaho anho) narrates
that he heard Rasulullah (Sallallahu Alaihi Wasallam) saying:

How excellent are five things!
and how heavy on the scale:

(1) Subhanallah
(Glory be to Allah Who is above all faults)

(2) Alhamdulillah
(Praise be to Allah)

(3) La ilaha illallah
(There is none worthy of worship except Allah)

(4) Allahuakbar
( Allah is the Greatest )

(5) A righteous son of a Muslim dies and he
forbears patiently expecting a reward in return.
