Seven years later, while trying to save Prem and Vinod from a probable accident, Vivek is injured which leaves his right arm partially paralyzed.

Vinod is secretly in love with Sapna who is the daughter of Ramkishan's former neighbor in his ancestral village, Dharamraj Bajpai.

Eventually, Prem and Preeti find out about Vinod and Sapna during a family outing and Vivek's and Sadhna's honeymoon at Rampur, which they both get engaged as well.

Meanwhile, her three friends and Dharamraj fill her head with thoughts as to why Vivek should be in charge of the family business and the company as the managing director.

Heartbroken, after finding out about it, Vivek asks Ramkishan to put Prem in charge of the family business and the company as the managing director and moves back to their ancestral village Rampur with a pregnant Sadhna to take care of the new factory.

Hum Saath-Saath Hain: We Stand United's concept was conceived by Sooraj Barjatya, who wanted to make a family drama.

[16] Reema Lagoo (as Mamta), Alok Nath (as Ramkishan), Himani Shivpuri (as Neenakshi), Satish Shah (as Pritam) and Ajit Vachani (as Pranab) were cast.

For Salman, Lagoo, Nath, Bahl, and Vachani, it was their third film with Barjatya after Maine Pyar Kiya.

Mandore Gardens, Mehrangarh Fort, and Jaswant Thada, were some of the locations in Jodhpur where the film was shot.

[38] The Barjatyas were quite press-friendly during the making of their previous films, but for Hum Saath-Saath Hain, the press screening was restricted to an elite few.

[31] During the Jodhpur film schedule in 1998, some members of the cast, Salman Khan, Saif Ali Khan, Neelam Kothari, Tabu, and Sonali Bendre, were involved in a case of shooting of an endangered black buck on a hunting expedition, on the outskirts of Kankani village in Jodhpur district of Rajasthan.

[39][40][41] The incident generated significant press coverage and Salman Khan spent a week in Jodhpur jail in 2007, before the court granted him bail.

[43][44] In 2019, Rajasthan High Court issued a notice challenging the acquittal of Sonali Bendre, Tabu and Saif.

Raamlakshman had composed as many as 27 tunes, out of which the soundtrack of the film features seven songs and playback singers: Kavita Krishnamurthy (for Karishma Kapoor), Alka Yagnik (for Sonali Bendre), Anuradha Paudwal (for Tabu), Kumar Sanu (for Salman Khan), Udit Narayan (for Saif Ali Khan), Hariharan (for Mohnish Behl), Sonu Nigam (for Shakti Kapoor), Hema Sardesai (for Neelam), Roop Kumar Rathod (for Ajit Vachani) and Pratima Rao (for Himani Shivpuri).

[47] The remaining songs on the album include the title track "Hum Saath Saath Hain", the wedding tracks "Chhote Chhote Bhaiyon Ke" and "Sunoji Dulhan", "Yeh To Sach Hai Ki Bhagwan Hai", "Mhare Hiwda" and "Maiyya Yashoda".

According to Box Office India, the soundtrack of Hum Saath-Saath Hain went on to sell 18 lakh (1.8 million) units, becoming the twelfth best-selling album of the year.

[53][33] Following all the post-production, cinematography, choreography and other things were completed, the film finally hit the theatre screens on 5 November 1999 during Diwali.

[56][57] Anupama Chopra of India Today noted, "A time-warped patriarchal fantasy, but somehow HSSH glows with Barjatya's conviction.

"[51] Alok Kumar of PlanetBollywood.com wrote, "Hum Saath-Saath Hain is repetitive, sickeningly sweet, and sappy.

"[59] Hum Saath-Saath Hain became the highest-grossing film of the year, with a worldwide gross of ₹81.71 crore (US$18.98 million).

[64] Hum Saath-Saath Hain remains one of the most popular family drama film of Indian cinema.

[76][77] Navya Kharbanda of Hindustan Times termed it a "cinematic masterpiece" and stated, "The film continues to captivate audiences with its themes of family bonds, love, and traditions.

"[78] Aakriti Anand of Filmfare stated that the film justified its title "to the fullest" and termed it an "out-and-out family entertainer".

Songs like "Sunoji Dulhan", "Mhare Hiwda" and "Maiyya Yashoda" have become synonym with the wedding, monsoon and festive seasons.
