Sheikh Ahmed Yassin played a renewing role for the insightful Islamic jihad and revived the spirit of religiosity in Palestine. Yassin rebuilt the Brotherhood thought as the martyr Imam Hassan al-Banna had left it before it was overshadowed by the veils of coercions.
Professor Yahya Al-Sanwar believes that the most prominent transformation brought about by Sheikh Yassin was his instilling a spirit of challenge with the Zionists in the occupied territories. He says that the Islamists did not realize the seriousness of these intoxications and obstacles until after more than four months of fierce war on Gaza.
