Dear brother Fadly read the following Fatwa and see if its similar to your case or not
Dear brother Mustafa we are not scholars...remember!
Shaykh al-Islam [Ibn Taymiyah – may Allaah have mercy on him] was asked whether it is permissible for a soldier to wear silk or gold or silver when fighting or when the envoys of the enemy come to the Muslims.
Praise be to Allaah. With regard to wearing silk in order to frighten the enemy, there are two scholarly views, the more correct of which is that it is allowed. The soldiers of Syria wrote to ‘Umar ibn al-Khattaab saying: “When we met the enemy we saw that they had covered their weapons with silk and we found that this struck terror in our hearts.” ‘Umar wrote back to them saying: “You should cover your weapons as they do.” And wearing silk is a kind of showing off, and Allaah likes showing off at the time of fighting, as it is narrated in al-Sunan that the Prophet (peace and blessings of Allaah be upon him) said: “There is a kind of showing off that Allaah likes, and a kind of showing off that Allaah hates. The showing off that Allaah likes is when a man shows off at the time of war. The kind of showing off that Allaah hates is showing off for the purpose of pride and boasting.” On the day of Uhud, Abu Dujaanah al-Ansaari showed off among the ranks, and the Prophet (peace and blessings of Allaah be upon him) said: “This is a kind of walking that Allaah hates except in this situation.” Majmoo’ al-Fataawa, 28/17
