Alam was born and raised in Khulna, where she attended Pioneer Girls High School. By 2007, the year she was in sixth standard, she was playing both handball and volleyball for her school. She lived some distance away, and travelled there by rickshaw, a trip that would take about 40 to 50 minutes.[6]
Alam's interest in sports then attracted the attention of Sheikh Salahuddin, a player and coach of the Khulna Division men's cricket team, who lived opposite the school. Unlike the other school girls, who wore shalwar kameez, Alam would make her rickshaw trip to school in sports attire. Salauddin spotted her on some of her rickshaw journeys, and eventually asked her whether she wanted to play cricket. She immediately agreed.[6][7]
At that time, Alam was not a follower of cricket, and did not understand the rules. However, she was told that Bangladesh would soon have its own women's team, and that was an incentive for her to try out.[6]
Alam's parents were supportive.[6][7] "My father only told me to return home before the evening Azaan and not do anything that would bring shame to the family," she told CricTracker in 2020.[6] Even more supportive was her grandmother, who would take her to and from matches.[7]
In her initial cricket trials, Alam "failed miserably".[6] However, her coach had spotted that she had ample natural ability,[8] and she had always been fit.[6] After practising for a month, she became a fast bowler.[6][8] Shortly afterwards, she was the leading wicket-taker in a seven-team tournament, with 13 wickets, and was called up to the national camp.[6] Her prompt success at cricket caused some problems for her and her family:
"People around my locality ... told [my father] that I should continue with my studies and then get married. They were against me playing cricket, being a girl. My father defended me saying that I wasn't doing any wrong and he supported me. In the current society, supporting each other is very crucial. Not only girls, but even boys have had to sacrifice their passion for sports to continue studying."[6]
Alam did not, and does not, have a role model. In the first two years she was playing cricket, she was not able to follow the game very much. Then, one of her coaches showed her some YouTube videos of Brett Lee. The coach suggested that she generate more pace and swing by following Lee's bowling action. From then onwards, she would identify and follow two or three players "from every nation", but her one and only cricketing idol is Mashrafe Mortaza.[6]
Career
The first time Alam took the field for the national team was during a Hong Kong tour of Bangladesh in March 2008.[6][9] "When I was selected for Bangladesh, I had to ask my father whether I should play or do my exams?" she has said.[7] His response was "... you may only have one chance to play for your country but you will have 3 chances to pass your exam".[7]
Alam therefore played in all four of the matches in the unofficial 50-over format series.[9] During the last one, at Mirpur Stadium, she took a hat-trick with the only three balls she bowled,[10][11] in the 47th over,[6][7][12] a feat that caused quite a stir:
"... there was a lot of buzz around. My picture was there in the first page of the newspaper and from then onwards, people’s perception started changing. They called me the pride of Khulna, the pride of Bangladesh."[6]
In October 2018, she was named in Bangladesh's squad for the 2018 ICC Women's World Twenty20 tournament in the West Indies.[18][19] She was the joint-leading wicket-taker for Bangladesh in the tournament, with six dismissals in four matches.[20] Following the conclusion of the tournament, she was named as the standout player in the team by the International Cricket Council (ICC).[21]
