[PRINCE SHAAN]

Sa`d bin Abu Waqqas ( radi Allahu anhu ) reported:
The Messenger of Allah (Sall-Allahu alayhi wa sallam) said,

"He who says after the Adhan:

`Ash-hadu an la ilaha illallah Wah-dahu la sharika Lahu;
wa ash-hadu anna Muhammadan `abduhu wa Rasuluhu,
radhitu Billahi Rabban,
wa bi Muhammadin Rasulan,
wa bil Islami Dinan

[I testify that there is no true god except Allah Alone;
He has no partners and that Muhammad (Sallallahu alaihi wasallam)
is His slave and Messenger;
I am content with Allah (Azza wa Jall) as my Rubb,
with Muhammad (sallal laahu alaihi wasallam) as my Messenger
and with Islam as my Deen],'

his sins will be forgiven.''
