Ruhma Carter (also Hanif) is a fictional character from the BBC soap opera Doctors, portrayed by Bharti Patel. Ruhma's storylines in the programme have included her relationship with Heston Carter (Owen Brenman), dealing with her partial deafness, supporting her children through various issues with the police, mourning the loss of Heston after his shock death and being suspended from her job.

Ruhma is characterised as a forthright, opinionated and working class character with an unexpected "grim past". Her backstory involves being in an abusive marriage which she had to flee from with her children. That experience, alongside raising her children as a single mother and her husband Heston dying, leaves Ruhma finding solace in her job as a midwife. When she is temporarily suspended from her job, scenes of Ruhma going through her "lowest point" aired. For her portrayal of Ruhma, Patel has received various award nominations, including the British Soap Awards for Best Newcomer and Best Actress.

The BBC described Ruhma as "a midwife who promises to deliver a refreshing perspective on all things pregnancy related." In an interview with the BBC, Patel stated that her character is "a woman's woman" and that Ruhma believes a pregnant woman should have an enjoyable and natural experience. Patel added that her character wants to promote more midwife-led home births and that she will fight a good fight for her cause.

When Ruhma is introduced, she was characterised as a forthright, opinionated and working class person. It was said that these traits help to cover her "grim past". Her first BBC profile explained that Ruhma is more comfortable in the company of women, but noted that she is not nervous when around men. Ruhma loves bargains and enjoys shopping at charity shops and car boot sales, but is also interested in opera, classical music and live performances, but does not have the money to pursue those interests. In regards to raising her children, the profile stated that Ruhma raised them in a "rather liberal" way as opposed to her own upbringing. The profile added that Ruhma is "outgoing, funny, extremely warm and very front-foot" and that she has a great sense of humour.

Patel stated that Ruhma is a good person. She said that Ruhma's job is important to her, describing it as "her rock". She explained that when Ruhma was leaving her abusive marriage, raising her kids as a single mother, and through her grief for Heston, Ruhma's job was "everything for her and the one thing she could lose herself in". When Ruhma is suspended from her job, Patel noted the tough time that her character has gone through, describing it as "a terrible time" and the lowest point for her. Patel commented: "She was trying to help someone, and it backfired, and now Carrie and Doug have blamed her for the traumatic birth of their son". Over her tenure, scenes see Ruhma become slightly "over familiar and needy".

Upon being asked about Ruhma potentially having a love interest, Patel commented "Honestly, I doubt it; she's a very busy independent woman [...] If it were to happen I think it would be a bolt out the blue, Ruhma isn't looking and it's not on her radar at all." However, when Ruhma saves a pregnant patient of Heston's, Ellen Markwardt of What's on TV stated "Ruhma has made a real impression on the GP." When Ruhma is introduced to Heston, the pair initially dislike each other, resulting in an argument that ends in a kiss. After his death, Patel stated that Ruhma is "lonely, and is still relatively young", and would "like the idea of finding love again, but she'd also be nervous".

Ruhma is introduced as a sonographer for Emma Reid (Dido Miles) and Howard Bellamy (Ian Kelsey) and it is explained that her and Emma are former colleagues. Mrs Tembe (Lorna Laidlaw) calls her into the Mill, and whilst waiting, a pregnant patient of Sid Vere's (Ashley Rice) begins to feel ill, so she treats her. When Jimmi Clay (Adrian Lewis Morgan) and Heston Carter (Owen Brenman) hear of Ruhma's potential hiring, they disagree, insisting that the Mill does not need a midwife. However, Mrs Tembe disagrees and appoints Ruhma. Ruhma and Heston attend the theatre together and he later takes her on a date to a restaurant. Heston asks Ruhma to his house for dinner, where she explains her housing difficulties. Heston invites her to live with him, so Ruhma and her children, Shak (Sunjay Midda) and Alia (Mandy Thandi), go to live with him.

Ruhma plans to propose to Heston on her birthday, while Heston has the same idea. He proposes to Ruhma in a restaurant by arranging a Bollywood style dance routine and she says yes. After the pair become engaged, Shak expresses his unhappiness with the wedding. Ruhma receives a tip-off that she could sell furniture from people's estates. She sells the furniture online to make money for the wedding. On their wedding day, the police arrive at the venue and take Ruhma in for questioning. They accuse her of stealing the items and selling them for a monetary gain, to which she refuses and insists that she had no knowledge of the items being stolen. She is eventually released, but due to the ordeal, they are unable to sign the register, meaning they not legally married. They rush to the registry office when there is a cancellation and sign it. When Ruhma mishears Ayesha Lee (Laura Rollins) and Al Haskey (Ian Midlane), she reveals that she is losing her hearing. Heston suggests seeking treatment from a private audiologist and although she initially disagrees due to pledging loyalty to the NHS, she later seeks private help.
