Jarallah was born in Jerusalem and was educated at the al-Azhar University in Cairo, Egypt.
Politically, he was an ally of the Nashashibis and a rival of the al-Husaynis. When Kamil al-Husayni died in 1921, Jarallah had significant support from the ulema in Jerusalem to succeed al-Husayni as Grand Mufti. After Jordan occupied Jerusalem in 1948, Abdullah I of Jordan appointed Jarallah in his place on 20 December 1948.
Jarallah was the Grand Mufti until his death. No Grand Mufti was appointed to replace Jarallah until Yasser Arafat appointed Sulaiman Ja'abari in 1993.
