== Keaslian Dokumen == Robert Spencer direktur jihadwatch.org meragukan keaslian naskah ini dengan alasan bahwa pada waktu Muhammad meninggal, mesir belum ditaklukan oleh tentara islam, jadi tidak jelas umat kristiani manakah yang diaebut dalam naskah tersebut. Kemudian juga ada penggambaran mesjid dengan menara dimana menara masjid baru diadakan di masjid jauh setelah Muhammad meninggal. <ref>https://pjmedia.com/lifestyle/2014/1/26/the-hypocrisy-of-the-huffington-posts-praise-of-muhammad/2/</ref>
== Keaslian Dokumen ==
Uji keaslian dari surat jaminan ini sudah dilakukan oleh beberapa peneliti. Robert Spencer salah satunya dengan catatan sebagaimana berikut:
{{Quote|Muhammad is supposed to have died in 632; the Muslims conquered Egypt between 639 and 641. The document says of the Christians, “No one shall bear arms against them.” So were the conquerors transgressing against Muhammad’s command[?]...Did Muhammad draw up this document because he foresaw the Muslim invasion of Egypt? There is no mention of this document in any remotely contemporary Islamic sources; among other anomalies, it bears a drawing of a mosque with a minaret, although minarets weren’t put on mosques until long after the time Muhammad is supposed to have lived, which is why Muslim hardliners consider them unacceptable innovation (bid’a)...The Achtiname, in short, bears all the earmarks of being an early medieval Christian forgery, perhaps developed by the monks themselves in order to protect the monastery and Egyptian Christians from the depredations of zealous Muslims.<ref>Spencer, Robert (January 26, 2014).
