Musa Jahni narrates from Mus'ab bin Sa'd, and he from his father, Sayyiduna Sa'd (may Allah be pleased with him), that he said: A Bedouin came to the Messenger of Allah (peace and blessings be upon him) and said, "Tell me some words which I may say." The Prophet (peace and blessings be upon him) said, "Say: 'La ilaha illallah ...' (till the end of the supplication)." The Bedouin said, "In these words, there is praise of my Lord; tell me something for myself." So the Prophet (peace and blessings be upon him) said, "Say: 'Allahumma ighfir li ...' (till the end)." (The narrator of the hadith) Musa said: I think the word "aafini" (grant me well-being) is included, but I do not remember whether it is established from the Prophet (peace and blessings be upon him) or not.

Sayyiduna Abu Dharr (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings be upon him) said: Shall I not tell you the words that are most beloved to Allah? I said: O Messenger of Allah! Tell me the words that are most beloved to Allah. He (peace and blessings be upon him) said: The words most beloved to Allah are: "Subhan Allah wa bihamdihi."

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Whoever says these words a hundred times in a day—"(La ilaha illallah wahdahu...)" to the end—he will have a reward equal to freeing ten slaves, a hundred good deeds will be written for him, a hundred sins will be erased from him, he will be protected from Satan all day until evening, and no one will bring a deed better than this on the Day of Judgment except someone who does more than this (i.e., recites this tasbih more than a hundred times and does more good deeds). And whoever says "(Subhan Allah wa bihamdihi)" a hundred times in a day, his sins will be forgiven even if they are as much as the foam of the sea.

Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) says: We were with the Messenger of Allah (peace and blessings be upon him) when he said:“Is any one of you incapable of doing a thousand good deeds every day?”One of those sitting with him said:“How can any one of us do a thousand good deeds?”He (peace and blessings be upon him) said:“If he says ‘Subhan Allah’ one hundred times, a thousand good deeds will be written for him and a thousand sins will be erased from him.”
