Membership of Hezbollah wasn't easy. It required intense steps and the process was no different for Syed Hadi Nasrallah. Intelligence officials of Hezbollah called him for an interview and a thorough systematic investigation. He responded with a smile, "I am the son of Syed Hasan Nasrallah." He was told, "It does not matter. Write out your detailed personal information." Hadi went to his father and asked, "Father, did you give orders that have bothered me and would not let me into the group?" Syed Hasan Nasrallah replied, "Such is the system of resistance and we must comply." And so, Hadi had to fill a lengthy form and write 14 pages about himself before being recruited within Hezbollah.
On September 12, 1997 three Hezbollah fighters attacked an Israeli army base in the Zionist occupied province of Aqleem Al Tafah in South Lebanon. They took the army base by surprise. In the wee hours of September 13, the Israeli army martyred the three Hezbollah fighters and six Lebanese soldiers in the mountains of southern Lebanon. Their bodies were in possession of Israeli forces. Hezbollah officials viewed the video footage of the bodies after Israeli television displayed their images and confirmed that one of the martyrs was Syed Hadi Nasrallah, son of the Hezbollah leader and Secretary-General, Syed Hassan Nasrallah. The news spread like wild fire across Lebanon and the Middle-East. Hadi was 18.
It was like a bombshell in the Lebanese society. In the history of the country, both during the Civil War and the confrontation with Israel, never did the son of any political or military leader undertake a mission as dangerous as this. In fact, nowhere can we imagine the concept of equitability rising to such heights. Writes New Republic: "In the days after Hadi was killed, Lebanese leaders from across the political spectrum—even Christian warlord and bitter enemy Elie Hobeika—paid their respects to Nasrallah and his wife."
According to reports, Hadi's remains were sent to his family for burial nearly a month after his martyrdom.
