Abu Hurairah (Radhi-Allahu 'anhu) reported:
The Messenger of Allah (Sallallaahu 'alaihi wasallam) said,
"He who recites in the morning and in the evening the statement:
One Hundred Times, will not be surpassed on the Day of Resurrection by anyone with better deeds than one who utters the same words or utters more of these words.''
[Sahih Muslim - Book 35 - Hadith 6509]
The Messenger of Allah (Sallallaahu 'alaihi wasallam) said,
"He who recites in the morning and in the evening the statement:
سُبْحَانَ
اللهِ وَبِحَمْدِهِ
`Subhan-Allahi wa bihamdihi
(Allah is free from imperfection and I begin with praising Him)'
[Sahih Muslim - Book 35 - Hadith 6509]
