T-S Ar.39.492
Letter from a man to his son. In Arabic script. The address is rubbed out, although the word thaghr is still legible, so it was probably sent to either Fustat or Alexandria. After about 10 lines of prologue, the sender complains about the lack of letters; reports that the addressee's paternal aunt died, and her inheritance is in the hands of the government ("aṣḥāb al-mawārīth"). Also, the addressee's brother has had a son in Qūṣ. The rest of the letter mentions an upcoming holiday a few times. (Information in part from Goitein's index card.) Merits further examination.
