All Palestinian mujahidin and all believers throughout the Islamic world are obliged to do whatever they can to defend the women, the children and the vulnerable people of Gaza. Whoever is killed carrying out this noble and sacred duty dies a martyr, and may he be raised up with the martyrs of Badr and Uhud who fought alongside the Messenger of Allah SAAW.
