The Muslim community has been on edge since June 6 when a family of five was struck by a driver in London, Ont. in a deadly attack police have said was motivated by hatred of Muslims.
Police said all those injured in the 2.30 p.m. (1230 GMT) attack in the Dine Hoxha moaque in downtown Tirana had been hospitalised.
The hearings were adjourned until Wednesday morning.
At least 19 people have been injured as a result of the blast.
The suspects were identified as Iqbal, Rizwan and Muneer.
Muslim faithful arrived by bus, car or on foot in the poor district of Bopp, home to the new Massalikul Jinaan mosque, capable of hosting 30,000 worshippers.
The work is expected to be completed by the end of 2020
