The Messenger of Allah (Sall'Allahu alaihi wa sallam) said,
"There are two statements that are light for
the tongue to remember,heavy in the scales
and are dear to the Merciful:
'Subhan-Allahi wa bihamdihi, Subhan-Allahil-Azim'
'(Glory be to Allah and His is the praise,
(and) Allah, the Greatest is free from imperfection)'.''
[Al-Bukhari and Muslim].
