The Messenger of Allah (PBUH) 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)'."

[Muslim].

The Messenger of Allah (PBUH) said, "There are two statements that are light for the tongue to remember, heavy in the Scales and are dear to the Merciful: 'Subhan-Allahi wa bihamdihi, Subhan-Allahil-Azim [Glory be to Allah and His is the praise, (and) Allah, the Greatest is free from imperfection]'."

[Al-Bukhari and Muslim].

“Subhan Allahi Rabbil-‘alamin (Glory is to Allah, the Lord of the worlds),” repeating that for a while, then he said: Subhan Allahi wa bihamdihi (Glory and praise is to Allah).”

Prior to his demise, the Messenger of Allah (PBUH) used to supplicate frequently: Subhan Allahi wa bihamdihi; Astaghfirullaha wa atubu ilaihi (Allah is free from imperfection, and I begin with praising Him. I beg forgiveness from Allah and I turn to Him in repentance."

[Al-Bukhari and Muslim].

The Messenger of Allah (PBUH) said, "He who recites in the morning and in the evening the statement: 'Subhan-Allahi wa bihamdihi (Allah is free from imperfection and I begin with praising Him)' 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."

[Muslim].

The Messenger of Allah (may peace be upon him) recited often these words: Hallowed be Allah and with His praise, I seek the forgiveness of Allah and return to Him. She said: I asked: Messenger of Allah, I see that you often repeat the saying" subhan allahi bihamdihi astag firullahi watubuilaih" whereupon he said: My Lord informed me that I would soon see a sign in my Ummah, so when I see it I often recite (these) words: Hallowed be Allah and with His Praise, I seek forgiveness of Allah and return to Him. Indeed I saw it (when this verse) was revealed:" When Allah's help and victory came, it marked the victory of Mecca, and you see people entering into Allah's religion in troops, celebrate the praise of Thy Lord and ask His forgiveness. Surely He is ever returning to Mercy."

The Prophet (PBUH) came out from my apartment in the morning as I was busy in performing the dawn prayer. He came back in the forenoon and found me sitting there. The Prophet (PBUH) said, "Are you still in the same position as I left you." I replied in the affirmative. Thereupon the Prophet said, "I recited four words three times after I had left you. If these are to be weighed against all you have recited since morning, these will be heavier. These are: Subhan-Allahi wa bihamdihi, `adada khalqihi, wa rida nafsihi, wa zinatah `arshihi, wa midada kalimatihi [Allah is free from imperfection and I begin with His praise, as many times as the number of His creatures, in accordance with His Good Pleasure, equal to the weight of His Throne and equal to the ink that may be used in recording the words (for His Praise)]."

[Muslim].

The Messenger of Allah (PBUH) said, "He who utters a hundred times in a day these words: 'La ilaha illallahu, wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu, wa Huwa 'ala kulli sha'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),' he will have a reward equivalent to that for emancipating ten slaves, a hundred good deeds will be recorded to his credit, hundred of his sins will be blotted out from his scroll, and he will be safeguarded against the devil on that day till the evening; and no one will exceed him in doing more excellent good deeds except someone who has recited these words more often than him. And he who utters: 'Subhan-Allahi wa bihamdihi (Allah is free from imperfection and His is the praise)' one hundred times a day, his sins will be obliterated even if they are equal to the extent of the foam of the ocean."

[Al-Bukhari and Muslim].
