Opting to bat in their last league match, the defending champions posted a mammoth 301 for six, before bowling out their hapless opponents for just 56 in 28.2 overs at the Sharjah Cricket Stadium.
The convincing win ensured India topped the group.
Samson, who plays for Rajasthan Royals in the Indian Premier League (IPL), led the way with a blistering 85 off 48 balls, smashing eight fours and four sixes during his stay at the crease.
The Indians were off to a sedate start with openers Ankush Bains (59) and Akhil Herwadkar (37) sharing 58 runs in just under 12 overs.
Skipper Vijay Zol contributed 35 off 68 balls, but the momentum that the holders were looking for came only after the arrival of Samson at the crease.
