It was used for writing the Old South Arabian languages Sabaic, Qatabanic, Hadramautic, Minaean, Hasaitic, and Geʽez in Dʿmt.

The earliest instances of the Ancient South Arabian script are painted pottery sherds from Raybun in Hadhramaut in Yemen, which are dated to the late 2nd millennium BCE.

[8] For example, ‏𐩿𐩭𐩽𐩽𐩿‎ These signs are used in an additive system similar to Roman numerals to represent any number (excluding zero).

The difference between the two is that Musnad documented historical events, meanwhile Zabur writings were used for religious scripts or to record daily transactions among ancient Yemenis.

[8] Yemeni archeologist and linguist Mutaher al-Eryani, was keen to record a memorial in the Musnad script and in the Sabaean language, commemorating the renovation of the Ma’rib Dam in 1986, which was carried out at the expense of Sheikh Zayed and in conjunction with the celebration of victory in the North Yemen Civil War against the Kingdom of Yemen.
