This papyrus has frayed edges at top which makes it impossible to determine its true significance. The remaining thirteen lines has four sets of different entries without diacritical points. Some of these readings are disputed.

This document belongs to the category of acknowledgement of debts. There are a growing number of very early papyri that can now be placed into this category whose geographic scope is early Islamic Egypt and Palestine. A unique aspect of these group of documents is that they bear witness to a previously unattested calendar designation, expressed variously as abbreviated sanat (year/calendar), to qaḍāʾ al-muʾminīn (decree/reckoning/jurisdiction of the believers) and sanat qaḍāʾ al-muʾminīn (year of the decree/reckoning/jurisdiction of the believers). qaḍāʾ has been variously interpreted as jurisdiction (Rāġib), reckoning (Shaddel), and decree (Tillier and Vanthieghem), each of which carry their own specific nuances.[2] All agree however that the phrase references a calendar system.[3]

Based exclusively on the earliest documentary evidence available, there can be no doubt that the calendar system adopted by the early Muslims, however it may have been designated, began in the year 622 CE (i.e., year 1). Excluding Arabic-only papyri, there are dozens of Greek, Greek-Coptic and Greek-Arabic fiscal papyri showing a hijra year in addition to a Byzantine indiction.[4] Likewise, similar examples can be found in Christian Syriac manuscripts showing hijra dates alongside the Seleucid era.[5] There is also a unique triple dated early inscription from 662 CE, showing a hijra date, Byzantine indiction and year of the colony of Gadara.[6] When the dates of all the aforementioned documents are independently calculated and calibrated against each other, they almost always correspond to 622 CE / 1 AH.[7]

Documents containing the abbreviated phrase sanat or qaḍāʾ al-muʾminīn or sanat qaḍāʾ al-muʾminīn have come from around 20 AH, 42 AH, c. 44 AH, 48 AH, and two (1, 2) from 57 AH.

[3] Bruning disagrees and asserts that s.n.t. should be read as sunnatan and proposes P. Louvre Inv. E 7106 contains a previously unattested validity clause that is identifiable in three different versions - that is, not a previously unattested calendar designation. Here the shorter variant sunnatan ("in accordance with normative precedent") is present. The other two versions that are contained in documents dated 42 AH and 57 AH respectively are sunnat qaḍāʾ al-muʾminīn ("in accordance with the normative procedure of the believers") and qaḍāʾ al-muʾminīn ("in accordance with the procedure of the believers"). Their purpose is to state the validity of the aforementioned financial transaction. See J. Bruning, "A Legal Sunna In Dhikr Ḥaqqs From Sufyanid Egypt", Islamic Law And Society, 2015, Volume 22, pp. 352-374.

[7] Where they do not match, on occasion it seems to be a mistake on behalf of the scribe caused by a lack of familiarity with the hijra calendar (e.g., lunar not solar calendar).
