Leading Palestinian Islamic scholar and member of parliament Hamed al-Betawi died on Wednesday after undergoing heart surgery, Hamas officials said.
Sheikh Al-Betawi, 68, from Nablus, was elected to the Palestinian Legislative Council in 2006 as a member of the Hamas-affiliated Change and Reform Bloc.
A revered Allama (scholar), Al-Betawi was jailed by Israel several times.
His son Fadel Beitawi, 33, was detained in an Israeli night raid on Nablus on Monday night, locals said.
The sheikh underwent heart surgery two weeks ago, and died in al-Maqased hospital in Al-Quds.
