VIRTUES OF 'SUBAHANALLAHI WABIHAMDIHI'

Narrated by Abu Huraira (may Allah be pleased with him): The Prophet (peace and blessings of Allah be upon him) said, "There are two expressions which are very easy for the tongue to say, but they are very heavy in the balance and are very dear to The Beneficent (Allah), and they are, 

سبحان الله وبحمده سبحان الله العظيم

Subhan-Allahi wa bihamdihi, Subhan-Allahil-Azim

[Glory be to Allah and His is the praise, (and) Allah, the Greatest is free from imperfection)'.''

Sahih Bukhari (Volume 8, Book 78, #673)

Narrated by Abu Huraira (may Allah be pleased with him) Allah's Apostle (peace and blessings of Allah be upon him) said, "Whoever says, 'Subhan Allah wa bihamdihi,' one hundred times a day, will be forgiven all his sins even if they were as much as the foam of the sea. 
Sahih Bukhari (Volume 8, Book 75, #414)

Abu Dharr (May Allah be pleased with him) reported: The Messenger of Allah (peace and blessings of Allah be upon him) said to me, "Shall I tell you the expression that is most loved by Allah?'' It is `Subhan-Allahi wa bihamdihi' (Allah is free from imperfection and His is the praise)'."[Sahih Muslim]

Jabir (May Allah be pleased with him) reported: The Prophet (peace and blessings of Allah be upon him) said,

"For him who says: `Subhan-Allahi wa bi hamdihi (Allah is free from imperfection, and I begin with praising Him, and to Him),' a palm-tree will be planted in Jannah.'' [At-Tirmidhi]
