Back in 2007, a twenty-seven year old Abdur-Rehman made his Test debut for Pakistan in a game against South Africa in Karachi. Abdur-Rehman, or Manna as he is called by his fans, picked up 4 wickets, including Mark Boucher in the first innings of the game, cleaning up the tail. In the second innings he also picked up 4 wickets, but this time of Graeme Smith, Hashim Amla, AB de Vielliers and Andre Nel for the second time. He finished the game with 8 wickets for 210 runs, playing second spinner behind Danish Kaneria, who managed 5 wickets in the game.
He then played the second test of the series at Lahore. He again performed and picked up 3 wickets in the game. After picking up 11 wickets on flat decks against one of the best line-ups in the world, he was caste as a failure (Please ask the PCB and selectors why) and Manna was dropped from the team.
He made his comeback for the side under Misbah-ul-Haq's leadership in 2010 under extreme pressure. One problem was his age, at thirty years old, this was his last chance; perform or be gone forever. The other issue was Pakistan had lost their opening bowlers to spot-fixing and the bowling lineup looked weak. The entire pressure was on Umar Gul and Saeed Ajmal, the duo needed support and Manna had to stand up and be counted.
