Pakistan

Pakistan have done this thrice and Javed Miandad, arguably their finest batsmen, has been part of it twice, the joint-most of any player in the history of Tests. The first time two Pakistani batsman scored a double ton in the same innings was against India in 1983, a game that they won by an innings and 119 runs.
Miandad scored an unbeaten 280 while Mudassar Nazar scored 231 at the Niaz stadium in Hyderabad (Sind) as Pakistan declared on 581/3 before bowling out India for 189 and 273.
The second time was in 1985 when Miandad finished unbeaten on 203 after a 397-run partnership with Qasim Omar for the third wicket to help Pakistan draw the Test against Sri Lanka in Faisalabad.
Inzamam-ul-Haq and Ijaz Ahmed were double centurions the third time it happened. An unbeaten 200 from Inzamam and 211 from Ijaz Ahmed helped them beat Sri Lanka by an innings and 175 runs at Dhaka in 1999.
