2018–2019 After winning the U23 Iranian World Team Trials, Shabani made his international debut at the
2018 U23 World Championships, where he claimed a bronze medal.
2020–2021 After the
COVID-19 outbreak slowed down, Shabani competed at the Iranian World Team Trials in November 2020, in an attempt to qualify for the
Individual World Cup. After notably defeating
Mojtaba Goleij, he went on to violently upset the dominant
Mohammad Hossein Mohammadian twice in a row to claim the spot, although he ended up not being sent to the Individual World Cup. To start off 2021, Shabani claimed the
Asian Continental Championship. The Iranian Wrestling Federation decided that the
Poland Open (which took place on June 8) would decide the country's representative at the Summer Olympics, contested between Shabani,
Alireza Karimi and
Mohammad Hossein Mohammadian. After wins over
'19 World Championship medalist Magomedgadzhi Nurov and multiple–time Asian Championship medalist
Alisher Yergali, he was defeated by
Mohammad Hossein Mohammadian in a closely contested two–point final bout. This result determined Mohammadian as the representative for
Iran at the 2020 Summer Olympics. == Major results ==
