Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah (peace and blessings of Allaah be upon him) said,
"He who recites after every prayer:
Subhan-Allah (Allah is free from imperfection) thirty-three times;
Al-hamdu lillah (praise be to Allah) thirty-three times;
Allahu Akbar (Allah is Greatest) thirty-three times;
and completes the hundred with:
La ilaha illallahu, wahdahu la sharika lahu,
lahul-mulku wa lahul-hamdu,
wa Huwa `ala kulli shai'in Qadir
(there is no true god except Allah. He is One and
He has no partner with Him. His is the sovereignty
and His is the praise, and He is Omnipotent),
will have all his sins pardoned even if they may
be as large as the foam on the surface of the sea.''
[Muslim].
