Islam encourages us to have proficiency with weapons of war. The Holy Prophet sas said:
Prepare to meet them (the enemy) with as much strength as you can afford. Verily! Strength is in archery, strength is in archery, strength is in archery.(Sahih Muslim, Book 33, Hadith 241)
This emergency preparedness is not just for times of war, but for times of peace as well. The Holy Prophet sas said:
Lands shall be laid open to you, and Allah will suffice you (against your enemies), but none of you should neglect(Sahih Muslim, Book 33, Hadith 242)
practicinghis skill in archery.
It is mentioned in ahadith that it was the way of the Holy Prophet(Tafsir-e-Kabir, vol. 6, p. 303-304)
sasto always hold friendly competitions between his Companions during times of peace, wherein archery and other tactics of war and strength were exhibited. Once he held such games in the Masjid, and he sassaid to Hadrat ‘Aishah ra that if you want to watch then stand behind me and watch from over my shoulders. Hadrat ‘Aishah ra stood behind him sasand watched all of the feats of battle (Sahih al-Bukhari Kitabul- Eidain). It is established from this that Islam considers it necessary to keep women familiar with the tactics of war so that when the time comes she can protect herself and her country. If her heart trembles at the flash of a sword or if hearing the sound of a gun or cannon makesher blood go dry, then she cannot happily give her children permission to go into the battlefield, nor can she bravely take part in the defense of her country. But Hadrat ‘Aishah ra, upon seeing any scene of the battlefield, could never say that my heart is constricted, because the Holy Prophet sasshowed her the tactics of war and he would always keep one of his wives with him during war so that courage and bravery would develop in them as well.
