Help translating inscription on shamshir

[Ronin 47]

This is very interesting. I can read some of the Arabic dates, but I thought I had to be wrong when it came out to 1470, because of the shape of the blade, but thanks to Dom independently confirming the date there is know little doubt in my mind, that the date is 875 or 1470. I just recently got to see this sword again and it is definitely made out off Damascus steel as well as the hand guard, and if I was judging the patina on the hand guard like a tsuba I would say it is at least 500 years old. While there still is a possibility off this being a later fake, I wonder if this could be one of the blades captured by the Ottomans from the Mamluk's around 1516? Does anybody know of any swords from around this time period that state that they were made in Damascus or any sword at all that states it was made in Damascus? Once again Dom I just want to thank you very much for the translation, you have been extremely helpful.
