Sa`d bin Abu Waqqas (May Allah be pleased with him) reported:
The Prophet (peace and blessings of Allaah be upon him) 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 (peace and blessings of Allaah be upon him) is His
slave and Messenger; I am content with Allah as my Rubb,
with Muhammad as my Messenger and with Islam as my Deen],'
his sins will be forgiven.''
[Muslim].
