Anamul Haque top-scored with 44 as Bangladesh won with six overs to spare.
The opener hit the third six of his innings to seal victory as the hosts posted 78-1 at the National Stadium and avenged Bangladesh's defeat by Afghanistan in the Asia Cup this month.

Nepal scored 149-8 after being asked to bat first, as Gyanendra Malla top scored with 48 from 41 balls, including four fours and a six.
Hong Kong's response started badly when the first ball saw Irfan Ahmed feather a catch to wicketkeeper Subash Khakurel off the bowling of Paras Khadka.
Waqas Barkat (18) and Babar Hayat (20) then steadied the ship as Hong Kong reached 58 for 3 after nine overs.
But spinner Basant Regmi claimed two wickets in consecutive deliveries to spark a rout.
Fellow left-arm spinner Shakti Gauchan finished with 3-9 as Hong Kong collapsed to 69 all out in 17 overs, having lost their last seven wickets for just 11 runs.
