These commercial activities as a cause of hostility, Vaglieri argues, are similar to the economic causes behind persecutions in many other countries throughout history.
Similarly the Jews kept 20 bales of cloth and 500 cloaks for sale, and other luxury goods. Vaglieri suggests that it is more logical to assume that the weapons were stored in a depôt for future sale. In the past some scholars attempted to explain the presence of the weapons, suggesting that they were used for settling quarrels among the families of the community. The inhabitants had stored in a redoubt at Khaybar a siege-engine, swords, lances, shields and other weaponry.
In the seventh century, Khaybar was inhabited by Jews.
Main article: Jewish community of Khaybar The imposition of tribute by the Muslims onto the Jews served as a precedent for provisions in Islamic law, which requires the regular exaction of tribute-known as jizya-from dhimmi non-Muslim subjects living in areas under Muslim rule, as well as the confiscation of land belonging to non-Muslims to merge into the collective property of the Muslim community ( Ummah). The Jews of Khaybar continued to live on the oasis for several more years, until they were expelled by the second Rashidun Caliph, Umar. The battle ended with the surrender of the Khaybar Jews, who were then allowed to continue living in the region on the condition that they would give one-half of their produce to the Muslims. Vaglieri claims other motives for the Muslim offensive might have included the prestige that the engagement would confer upon Muhammad among his followers, as well as the booty which could be used to supplement future campaigns. Watt notes the presence in Khaybar of the Banu Nadir, who were working with neighbouring Arab tribes to protect themselves from Medina's Muslim community, who had earlier exiled Jewish tribes for violating the terms of the Charter of Medina and for conspiring to kill Muhammad. Islamic sources accuse the Jews of Khaybar of having plotted to unite with other Jewish tribes from Banu Wadi Qurra, Tayma and Fadak as well as with the Ghatafan (an Arab tribe) to mount an attack on Medina. According to Islamic sources, Muslim troops marched on Khaybar and attacked the native Jews who had barricaded themselves in forts. Jewish tribes reportedly arrived in the Hejaz region in the wake of the Jewish–Roman wars and introduced agriculture, putting them in a culturally, economically and politically dominant position. Al Hamrani said, “The success of the Department’s projects and activities during the current year reflects our common visions and strategic goals, which come in harmony to the directions of the wise leadership of our beloved country and contribute to its advancement to become one of the best countries in the world in various fields.The Battle of Khaybar ( Arabic: غَزْوَة خَيْبَر) was fought in 628 CE between the early Muslims led by Muhammad and Jews living in Khaybar, an oasis located 150 kilometres (93 mi) from Medina in the northwestern Arabian Peninsula (present-day Saudi Arabia). Abdullah Ahmed Al Hamrani, Director-General of Ajman DED, stressed during his speech at the ceremony that the Ajman DED is proud of its partners from various sectors because of their prominent and vital role and contributions in achieving its vision and strategic goals, which are linked with the strategic goals and vision of the emirate of Ajman.
