Jihadi announced the committee at a press conference at Khilgaon Chourasta Jaam-e Mosque in Dhaka.
He also announced a 16-member advisory committee and nine-member special committee.
All the leaders incorporated in the new committee are not involved in active politics and regarded as "Awami League government sympathisers", sources at Hefajat said.
Yusuf Madani -- son of the former amir of Hefajat, Shah Ahmad Shafi -- was included in the new committee.
On April 25, the central committee of the Qawmi madrasa-based Hefajat-e-Islam was dissolved.
Babunagari and Jihadi were amir and secretary general respectively of the dissolved committee.
After several hours, a five-member convening committee of Hefajat was announced with Babunagari and Jihadi as its convener and member-secretary.
