Abu Bakar Ba'asyir
On trial for series of church bombings in 2000.
Often linked to Bali bombings as he is accused of being JI's spiritual leader
Mr Rahman echoed last week's testimony by three other witnesses, in saying that the elderly cleric became the head of JI following the death of the previous leader, Abdullah Sugkar, in 1999.
Mr Ba'asyir is on trial for his alleged role in church bombings in 2000 and for allegedly planning to overthrow the government to establish an Islamic state.
He denies any wrongdoing, or that JI even exists. The group is agitating for an Islamic state across South East Asia.
Mr Rahman said that JI's operations chief at the time, Hambali, had ordered the church bombings, but that Mr Ba'asyir would have approved the attacks.
"An emir's approval is always sought," he said.
Both Mr Rahman and Agung Diyadi, another witness testifying from Malaysia, said that JI had also been involved in a Muslim-Christian war on Indonesia's Maluku islands, where about 10,000 people were killed between 1999 and 2002.
Mr Diyadi, an Indonesian, said, however, that he had no knowledge of any plans by Mr Ba'asyir to overthrow the Indonesian Government.
He said JI gave "assistance to oppressed people and military assistance to fight people who oppress Muslims".
Asked where, he replied: "The Malukus, Poso and the
Poso in Indonesia's Central Sulawesi province has also
been the scene of Muslim-Christian clashes.

and Islamic militants that have been linked to al-Qaeda.
Militants in the Philippines are believed to have established terror training camps on remote islands.
Mr Ba'asyir sat reading a copy of the Koran during Thursday's trial. His lawyers, who have disputed the use of witnesses from abroad, boycotted the hearing.
