This is a very nice example of a rehilted Persian Safawid shamshir. The Scabard would and hilt are ofcourse Ottomon, since these 2 dynasties unfortunately fought against each other a few times it is nothing unusual to see on side or another repurposing war bootie.
Anyways as requested there is the translation for the item.
بنده شاه ولایت عباس Banda e Shah e welaayat, 'Abaas. This means Slave of Shah e Welaayat 'Abaas (King 'Abaas Safawi) Shah e Welaayat is a Farsi name for Hazrat e Ali (RA) The Fourth Khalifa or the First Imam. Since the Safawids were fervent Shia's, this translation makes more sense. Note: This translation of this type of seal hereby nulifies any other translation of this seal
عمل اسد الله 'amal e Assadullah. Work of Assadullah, meaning he was the sword smith who made it or the sword smith whose shop this might have come out of.
The whole "ladder of Mohammad" does not make any sense since there is no such a thing as a "ladder of Mohammad" in the Islamic history, this is just some miss nomer. However ladder pattern or nardban (ladder in farsi) is an acceptable name for the ladder pattern.
