The cost of equipping and arming the Palestinian resistance factions in the Gaza Strip is estimated at more than 200 million dollars according to current estimates, and this large amount for the besieged resistance factions in the Gaza Strip would not have been available without the contribution of many wealthy Arabs and Muslims in supporting jihad in this land.
Despite the severe restrictions, and the pursuit by Israeli and American intelligence of all the movements of the resistance leaders in the Gaza Strip, especially the Izz al-Din al-Qassam Brigades, the Hamas movement and the rest of the Palestinian resistance factions succeeded in obtaining money from businessmen and wealthy people, including a rich man who requested to remain anonymous.
