Following his retirement, he joined the Indian Cricket League, captaining the Hyderabad Heroes in the inaugural edition of the Twenty20 competition.

Inzamam-ul-Haq is a prominent member of the Tablighi Jamaat, an Islamic missionary organisation, and remains an influential personality in Pakistan cricket.

[10] The youngest of five siblings (four brothers and one sister), his Syed family was called pir for its historical involvement in Sufism and the preaching of Islam, descending from Jamal-ud-Din Hansvi, a scholar and poet who was from the lineage of Abu Hanifa and a direct disciple of the famous 12th-century Sufi poet Baba Farid.

He joined Yorkshire County Cricket Club[17] as a replacement for Younus Khan who left to play for Pakistan in the 2007 ICC World Twenty20.

Inzamam also had his name in record books early on when he took wicket of his 1st ball in ODI cricket when he got Brian Lara caught behind.

[citation needed] Handpicked by former Pakistan captain Imran Khan for the 1992 Cricket World Cup in Australia and New Zealand, 22-year-old Inzamam was relatively unheard of before the tournament.

[22] These innings established Inzamam's billing as a big-game player, although he was unable to replicate his World Cup success in later tournaments.

[23] In total, Inzamam set a record for scoring the most half centuries in One Day Internationals, 83 – though this is now surpassed by Sachin Tendulkar, Jacques Kallis and Kumar Sangakkara.

In his final ODI for Pakistan, playing against Zimbabwe in the 2007 Cricket World Cup, he took three catches whilst fielding, including the last one of the match, ending his One Day career.

However, in subsequent matches he demonstrated vulnerability against swing bowling which resulted in his being dropped for the final Test of the series after averaging a lowly 13.20 runs per innings.

[27] One of particular note came against Australia in Karachi, 1994, when he made 58 not out with the tail and helped Pakistan to a one-wicket victory and a 1–0 series win.

He also scored a century (184 runs) in his 100th Test, becoming only the fifth player to do so (after Colin Cowdrey, Alec Stewart, Gordon Greenidge and Javed Miandad; Ricky Ponting and Joe Root have subsequently emulated the feat).

[40] His 118 against Australia in Hobart almost won the test for Pakistan but Adam Gilchrist's match winning 149 not out made the difference.

Only three players have captained Pakistan in more Test matches, but all have better win–loss records and only Imran Khan has a lower win percentage than Inzamam.

The Oval Test match in 2006 was poised as a victory for Pakistan before the controversy took place, and had it not occurred it is likely that Inzamam's record would have had one more win and one fewer loss.

After early failures in Australia, he took a depleted Pakistan side to India in 2005 and played an important role in securing a draw by winning the final test match from an unlikely position with an innings of 184 runs.

The latter part of Inzamam's tenure as Pakistan captain was less successful and the team was embroiled in many controversies culminating in a disappointingly early exit from the 2007 Cricket World Cup at the hands of lowly ranked Ireland.

In the 2007 Cricket World Cup, Inzamam captained the Pakistani team to its first loss to associate ICC member Ireland (on St Patrick's Day).

The announcement was made the same day that Bob Woolmer, Pakistan's coach, died in his hotel room in Kingston, Jamaica.

He dedicated his final ODI to Woolmer to whom he shared a good relationship with for three years and affectionately called him 'The Bob'.

In December 2012, Inzamam was appointed as a batting consultant to Pakistan's national team on a short-term basis in preparation for the 2013 tour of India.

[56] His contract was then renewed until December 2016 after the successful tour of Zimbabwe where they won both the ODIs and T20Is which was Afghanistan's first series win against a Test playing nation.

"[62] On Pakistan's 2006 tour of England, Inzamam captained a team that refused to re-enter the field after tea, on 20 August 2006 at The Oval after allegations of ball tampering from umpires Darrell Hair and Billy Doctrove.

On 28 September 2006 the allegations of ball-tampering were dismissed, however he was found guilty of bringing cricket into disrepute and given a four match One-Day International ban with immediate effect.

[64] The then-Pakistani President Pervez Musharraf expressed his concerns to the then-PCB chairman Nasim Ashraf, who warned Inzamam and told the players to stop public displays of religious beliefs.

[64] Late Pakistan coach Bob Woolmer also stated that while religion fostered a degree of unity, it also interfered in the team's training and practice sessions.

[65] In October 2023, it was reported that Inzamam was serving as a director of the UK-based Yazoo International Ltd.[66] He was alongside three others: Mohammad Rizwan, a member of the Pakistan national cricket team; Talha Rehmani, managing director of Saya Corporation; and Intisar-ul-Haq, Inzamam's brother, who serves as the company secretary.

[66][67] The association of a national cricket selector with both a player and an agency representative raised concerns over potential conflict of interest.
