Zakia Jafri had challenged the clean chit given by the Special Investigation Team (SIT) to Modi.
The verdict gave relief to Gujarat Chief Minister and BJP's prime ministerial candidate Narendra Modi.
BJP president Rajnath Singh said he congratulated Modi after the court gave its verdict.
Singh said the court's verdict was on the expected lines.
"I welcome the Ahmedabad court's verdict today which has given clean chit to Shri Narendra Modi. This verdict is on the expected lines and it vindicates our stand that the campaign against Modiji is politically motivated," Singh said in his Facebook post.
He further tweeted: "Congratulated Shri @narendramodi over the telephone after the court gave him clean chit today."
Welcoming the verdict, senior BJP leader Arun Jaitley said in his article: "There is a fundamental difference between truth and falsehood. Truth holds together. Falsehood is full of contradictions. It falls apart. This is exactly what has happened to a conspiracy of falsehood hatched by Narendra Modi's opponents in relation to the 2002 Gujarat riots. "
He said the Gujarat riots was a painful chapter in India's history.
"The Gujarat riots of 2002 are a painful chapter in recent Indian history. The burning of the Sabarmati Express and the subsequent riots have cost us many valuable lives, injured many and led to a large scale loss of property," Jaitley said.
"Regrettably, a charge has been made against the State Government led by Shri Narendra Modi that it was responsible for the conspiracy behind the riots. The truth is otherwise. The total number of persons arrested both for preventive and punitive actions are 1,00,488. This is more than the number of persons arrested in any other caste or religious tension in India. More people died in police firing during disturbances than in any other riot. This negates the allegation of police connivance. 4272 cases were registered. 1168 of these cases have been decided and hundreds of accused have been convicted. Most of these actions have been taken by the Gujarat Police," he said.
Jaitley slammed the ruling Congress and said for using investigative agencies against Modi to fight the political war against the BJP leader.
"The Congress Party and its sponsored NGOs are unable to fight Shri Narendra Modi politically. They have attempted to use the CBI, the SIT, petitioning before courts and a media campaign of vilification against him. None of these appears to have succeeded," Jaitley said.
"There were too many loopholes in the falsehood which was propounded. A small group of officers had guided this political strategy of the Congress and the NGOs. They fabricated evidences. Some websites conducted sting operations to substitute falsehood for truth," he said.
"Politically, Shri Narendra Modi emerges stronger in this adversity," he said.
The court on Thursday accepted the clean chit given to Modi by SIT in the 2002 riots case in the state
Following the court's decision, she told NDTV that she was saddened but not disheartened.
Her lawyer has reportedly said that they will contest the decision of the Ahmedabad court within a month.
In April, former Congress MP Ehsan Jafri's wife Zakia Jafri filed a protest petition in a Gujarat court against the SIT's closure report on the Gulbarg Housing Society massacre case.
The SIT report in the 2002 riots cases concerning the Gulbarg Society killings did not find any prosecutable evidence against Modi and 61 others.
The Supreme Court in February had allowed Zakia Jafri to file a fresh protest petition.
Zakia, the main petitioner in the Gulbarg Housing Society case, earlier said the Supreme Court appointed SIT gave her an incomplete copy of its closure report on the 2002 massacre.
She alleged around 20 pages of the closure report are missing from the copy that was handed over to her on May 7 last year.
An Ahmedabad court in April last year directed that Zakia Jafri should be given within a month a copy of the final report of the SIT on the Gulbarg Housing Society massacre in which her husband and Congress leader Ehsan Jafri was burnt to death.
The infamous Gujarat riots of 2002 left hundreds of Muslims dead, injured and tortured and came as a blot in the Bharatiya Janata Party (BJP) rule in the state.
The riots followed an incident of train burning in Godhra in which Hindus returning from Ayodhya were killed by a Muslim mob.
