The 1984 anti-Sikh riots have been a sensitive issue for people of Punjab, mainly the Sikhs, and is likely to damage the Congress' prospects in the state that will go to the polls in the last phase.
Owaisi was reacting to Modi slamming Congress President Rahul Gandhi's advisor Sam Pitroda for his remark on the anti-Sikh riots.
Randeep Surjewala said the party continued to support the quest for justice and stern punishment for those found guilty in the anti-Sikh riots, as also the subsequent acts of violence.
The BJP has demanded an apology from UPA chairperson Sonia Gandhi and Congress president Rahul Gandhi over Pitroda's remarks.
Prime Minister Modi slammed Congress and said that Sam Pitroda's words reflected the character and mentality and intentions of the grand old party.
In a video clip that was attached with Tewari's tweet, it was alleged that his father, late professor V N Tewari, was involved in the 1984 anti-Sikh riots in Delhi.
In November last year, the Delhi High Court had upheld its verdict in the case following which the convicted persons appealed in the Supreme Court.
The CBI told a bench of Justices S A Bobde and S A Nazeer that offence for which Kumar was convicted was of 'gruesome nature' as it was a 'genocide'.
The CBI told a bench of Justices S A Bobde and S A Nazeer that Kumar, who was a sitting MP in 1984, was the kingpin of the massacre of Sikhs in the national capital in 1984.
The violence had claimed 2,733 lives in Delhi alone.
The court has now posted the matter for April 9 for further proceedings in the case.
Justice Khanna had earlier also recused himself from hearing Kumar's appeal.
The CBI said that Kumar's 'political clout clouded fair and speedy investigation and derailed justice for the victims' of the 1984 anti-Sikh riots.
The case in which Kumar was convicted and sentenced relates to the killing of five Sikhs in Delhi Cantonment's Raj Nagar Part-I area of southwest Delhi on November 1-2, 1984.
