Umm Burayrah inscription

It was originally photographed and published by Muhammed Abdul Nayeem in 2000,[1] and was recently redocumented by the amateur archaeologist Saleh al‐Hwaiti.

[2] Though no date is found on the inscription, one proposal places it in the late sixth or early seventh century.

[2]Vocalized transliteration bi‐smika Allāhumma anā ʿAbd Šams br al‐Muġīrah, yastaġfir Rabbahu Translation

In your name, God, I, ʿAbd Šams, son of al‐Muġīrah, seek forgiveness from my Lord.The inscription is certainly monotheistic, calling for ʾistiġfār (the seeking of forgiveness) unattested in prior inscriptions and the use of rabb as a title for the deity Allāh.

Of the two, the latter is a likelier candidate for the ʿAbd Shams of the inscription as he was a contemporary of Muhammad.
