It was learnt that at least 50 people were killed after the suicide bomber attacked the crowed of Muslim worshippers.
Asked who was responsible, Abubakar said: "We all know the trend".
Haruna Furo, head of the Adamawa state emergency management agency, and Musa Hamad Bello, chairman of the Mubi north local government area, both confirmed the attack.
The latest Global Terrorism Index, published last week, said that deaths attributed to Boko Haram in 2016 fell by 80 percent.

It officially became time to look forward to 2018 when Major League Baseball announced its exhibition schedule on Monday. The Cubs and White Sox each released their 2018 spring training schedules Monday, and they'll meet three times .
But St-Pierre said despite this "Boko Haram remains an extremely potent and unsafe organisation" which was far from being "on the back foot", as the military has claimed. Boko Haram had even taken hold of the territory in 2014, but was pushed out by military troops the following year.
Boko Haram has waged an insurgency in northeast Nigeria since 2009 in its attempt to create an Islamic state in the region, killing more than 20,000 and forcing around 2 million people to flee their homes. The group held land around the size of Belgium in Borno, Adamawa and Yobe states until early 2015 but was forced out by Nigeria's army and troops from neighbouring countries.
Adamawa has been the scene of repeated attacks by insurgents in recent years.
Boko Haram fighters killed six farmers outside Maiduguri, the civilian militia and the brother of one of the victims said on Monday.
No-one has said they were behind the bombing but the Islamist militants Boko Haram typically target crowded places in northern Nigeria.
