Sword signed as Amal-e-Asadullah - Asda (Need Information)

[Ahad K.]

Hello friend,
I am presenting an antique sword in original condition, stamped or signed as Amal-e-Asadullah - Asda.
History says Hazrat Ali (RA) was prominent at the Battle of Uhud, as well as many other battles where he wielded a bifurcated sword known as Zulfiqar. He had the special role of protecting Prophet Muhammad (PBUH) when most of the Muslim army fled from the battle of Uhud and it was said "There is no brave youth except Ali and there is no sword which renders service except Zulfiqar." He was commander of the Muslim army in the Battle of Khaybar. Following this battle Prophet Mohammad (PBUH) gave Hazrat Ali (RA) the name Asadullah, which in Arabic means "Lion of Allah" or "Lion of God". Hazrat Ali (RA) also defended Prophet Muhammad (PBUH) in the Battle of Hunayn in 630.
I think this sword is not related to Asfahani Sword "the work of Assadullah of Isfahan".
According to the tradition of the Islam, the Prophet Muhammad has two swords. The first was a straight blade sword, common to the period, which is now shown in the Topkapi Palace Museum, Istanbul.
The second sword is believed to have a split blade. It was given to Hazrat Ali (RA), the Prophet son in low, who fought with it many great battles and seen great victories. The sword was nicknamed*Zulfikar* (Lord of cleaving).
This sword is lost, and no one really knows what was its shape.
Many attempts to describe the Zulfikar have been made during the development of Islamic swords.
Is this sword belongs to Hazrat Ali (R.A), Any idea?
