Is the following narration authentic: that Salman al-Farisi (may Allah be pleased with him) used to recite: "Al-Hamd, al-Hamad," so they said to the Messenger of Allah (peace be upon him), and he said: "Indeed, the 'Hamad' from Salman is more beloved to me than 'al-Hamd'"?

There is no hadith (definition) indicating the severe 'ajmah (non-Arabic accent/foreignness) of Salman al-Farsi, though some have attributed it to him, while other scholars have denied it. Al-Dhahabi mentioned in "Siyar A'lam al-Nubala'" from Abu Uthman al-Nahdi that Salman's speech was not understood due to the severity of his 'ajmah, and that he used to call wood "khushban" (a non-standard plural). Ibn Qutaybah denied this description, affirming that Salman's speech resembled that of the eloquent Arabs. Al-Dhahabi holds that the presence of eloquence does not contradict the presence of 'ajmah in pronunciation.
