All three were gone after nine overs, five of them fierce seam bowling by Amir, who was passed fit to play after missing the semifinals because of a back spasm.
Reprieved on three when he edged Jasprit Bumrah to wicketkeeper Mahendra Singh Dhoni only for television replays to show the fast-medium bowler had overstepped, Zaman blazed 114, laying the foundation for his team's formidable total of 338 for four and eventually earning the "Man of the Match" award.
Left-arm fast bowler Amir, whose career was nearly ended on the other side of London's River Thames by a ban and jail term he received for his part in a spot-fixing scam during a 2010 Test against England at Lord's, finished with three for 16. Rohit Sharma (0), Shikhar Dhawan (21) and Virat Kohli (5) were snuffed out by Amir in a devastating first spell with three brilliant deliveries.
At his post-match conference, the 30-year-old also hailed his young team's efforts through the tournament.
It was Pakistan's first global 50-over title since the 1992 World Cup and a sweet moment for a team who have been unable to host worldwide cricket in recent years due to security concerns.
Fakhar zaman could have been out but that ball turned out to be a no ball from Bumrah and after that there was no looking back for the opening batsmen as he went on to score an fantastic century which the world will remember for a long time. Obviously, the same bowlers are going to play, the same guys are going to bat.
Only The Indian Express full-throatedly acknowledge that Pakistan had out-classed India on Sunday.
Denied the calming influence of an early wicket, India's bowlers looked nervous.
The match turned out to be one of the most nightmarish under Virat Kohli's captaincy. "Just an incredible performance by Pakistan", former Sri Lanka skipper Kumar Sangakkara said.
"They made us make mistakes because of the way they were bowling and the way they applied pressure". He was picked for the Champions Trophy squad, missed the opening loss to India so didn't have any nightmares to process, then scored 31, 50, and 57 to cement his place.
Mohammed Amir and Hasan Ali took three wickets each, while Shadab Khan got two wickets.
Noboby gave Pakistan a prayer of winning this tournament as they came in the lowest ranked team and lost their opening game to India by a country mile but they have found a winning formula and played as a formidable unit.
He raised hopes of pulling off a one-man Indian Houdini act as he hit three successive sixes to reach his half century. India, the runners-up of the tournament, are one point behind Australia. After completing his century and adding 72 runs for the second wicket with Azam, Zaman tried to up the ante.
Earlier, playing his first one-day global tournament, the 27-year- old left-hander got a "life" when he was batting on four as Bumrah overstepped while M.S. Dhoni took a simple catch behind the stumps.
After Fakhar caused Azhar to be run out on 59, he took out his frustration on India, notably spinners Ravichandran Ashwin and Jadeja.
Sublime Fakhar leads Pakistan to 338-4 in ICC final
The "Law of Averages" were certainly going to catch up with India's "Big Three" after their brilliant run in the tournament. Most of his early runs came from the edge of his bat; then there would be an eyebrow-raising boundary of great audacity.
