Abdullah was born in July 19, 1960 to a conservative family. He entered Al-Khalil University to study Arabic studies but he did not complete his studies due to economic conditions. He was married with six sons and daughters.

His sister was the first to wear the hijab on her brother's advice. Abdullah was a devout worshiper who visited Al-Aqsa mosque frequently. Every year in the last 10 days of Ramadan, he performed his prayer in Al-Aqsa mosque. In addition to worship, he was keen to participate in cleaning the mosque, showing his humility.

His mother reported that Abdallah visited her four times a day despite his hard work and activities in the field of Resistance and Jihad.

Occupation forces attacked his house many times and arrested his four brothers just because they were Abdullah's brothers.

In his wedding on 14 November, 1986, he promised his wife to read one verse and to explain it. They had a promise to begin their life in the sake of Allah and to end it in the same aim. After his martyrdom, his wife said, "He an ideal husband, friend, and father. He did not hurt my feelings. He helped me in the house chores. He was a very good father in dealing with his children."

Abdallah was exiled to Lebanon with 400 Hamas leaders. He was arrested two times in occupation jails and once Palestinian jails. He was "wanted" since 1998. He was not seen in public since the operation of Adora which was conducted by the martyr Tarik Dofish, in April 2002, which resulted four Zionist soldiers killed and injuring 8.
