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.
