Nidal Fat’hi Rabah Farahat (Arabic: نضال فتحي رباح فرحات, romanized: Niḍāl Fatḥī Rabāḥ Faraḥāt; 8 April 1971 – 16 February 2003) created the Qassam rocket, a homemade weapon produced by Izz ad-Din al-Qassam Brigades.
At the beginning of Al-Aqsa Intifada, in 2000, Farahat officially joined the Izz ad-Din al-Qassam Brigades and soon became an active member in the organization, planning and carrying out numerous operations including mortar attacks on Jewish settlements in the Gaza strip.
[2] In 2001, Farahat, after several months of work, produced the first prototype for the Qassam rocket and presented it to Izz ad-Din al-Qassam Brigades leaders Salah Shahade and Adnan al-Ghoul.
Farahat also worked as a bombmaker, supplying Izz ad-Din al-Qassam Brigades militants with explosive devices and homemade rocket launchers like the Al-Bana and the Batar.
His three other brothers are alive, with one in prison since 1992 and the two others, Wissam Farhat and Momen Farahat, lived in the Gaza Strip where they assume high-ranking functions in the Izz ad-Din al-Qassam Brigades.
