Opener Tamim Iqbal struck the first Twenty20 international century by a Bangladesh batsman to help his team beat Oman by 54 runs under the Duckworth-Lewis method on Sunday and reach the Super 10 stage of the ICC World Twenty20.
The left-hander's 63-ball 103 not out, which was studded with five sixes and 10 fours, helped Group A favourites Bangladesh notch a huge 2-180 after being put in to bat.
Oman could only manage 9-65 in the rain-interrupted game after a revised target of 120 off 12 overs left them to score 75 off 22 balls.
Iqbal, who played some fine pull and lofted shots as well as some deft strikes behind the wicket, added 97 for the second wicket with Sabbir Rahman, who hit 44 from 26 deliveries.
Bangladesh's left-arm spinner Shakib Al Hasan later grabbed 4-15 as the team joined India, Pakistan, Australia and New Zealand in Group 2 of the main league, which starts on Tuesday.

"After a couple of boundaries I was hitting the ball nicely," said Iqbal, who scored 83 not out against the Netherlands and 47 versus Ireland in earlier games.
"I'd told my coach that I'll give you a hundred in this World Cup and I kept my promise."
Oman, who remained in contention after a surprise two-wicket win over Ireland, could not get the innings together in the face of an even stiffer target due to two rain stoppages during its innings.
In an earlier game, pace bowler Paul van Meekeren grabbed 4-11 as the Netherlands defeated Ireland by 12 runs.
Put in to bat, the Netherlands scored 5-59 with opener Stephen Myburgh striking an 18-ball 27 with five fours. Irish left-arm spinner George Dockrell took 3-7.
Ireland could only reach 4-47 in reply with Van Meekeren ending its hopes with the wickets of Max Sorensen (9) and George Dockrell (0) off consecutive deliveries in the last over.
