It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him), giving counsel to Sayyiduna Salman al-Khayr (al-Farisi) (may Allah be pleased with him), said: "O Salman! The Messenger of Allah wishes to give you words with which you may ask the Most Merciful, turn to Him in longing, and supplicate by them day and night. Say: 'Allahumma inni as'aluka sihhatan fi iman, wa imanan fi husni khuluq, wa najahan yatba'uhu falah, wa rahmatan minka wa 'afiyah, wa maghfiratan minka wa ridwana' (O Allah, I ask You for health and well-being along with faith, for complete faith along with good character, for success followed by prosperity, and for mercy, well-being, forgiveness and Your good pleasure from You)." This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Salman al-Farisi (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever says: 'Allahumma inni ushhiduka wa ushhidu mala'ikataka wa hamalata 'arshik, wa ushhidu man fis-samawati wa ushhidu man fil-ard, annaka antallahu la ilaha illa ant, wahdaka la sharika lak, wa ashhadu anna Muhammadan 'abduka wa rasuluk' (O Allah, I call You to witness, and I call to witness Your angels, the bearers of Your Throne, and all who are in the heavens and the earth, that You alone are Allah, there is no god but You, You are alone and have no partner, and I bear witness that Muhammad (peace and blessings be upon him) is Your servant and Messenger): whoever says it once, Allah frees one third of him from the Fire; whoever says it twice, Allah frees two thirds of him from the Fire; and whoever says it three times is freed from the Fire completely." This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.
