Khan is believed to be a close associate of the Pulwama attack mastermind Mudassir Ahmed Khan.
During the in-chamber proceedings Additional Sessions Judge Rakesh Syal allowed the anti-terror agency to quiz him in the case.
The National Investigation Agency (NIA) had sought his custody for 10 days from Additional Sessions Judge Rakesh Syal.
Advocate M S Khan, appearing for Sajjad Khan, opposed the agency's demand.
The National Investigation Agency told the court that the accused custody was required to unearth the deep-rooted conspiracy behind the February 14 attack in Pulwama that left 40 CRPF troopers dead.
Sajjad Khan (27), a resident of Pulwama was arrested near the Lajpat Rai market late Thursday night.
Mudassir had tasked him with establishing a sleeper cell in Delhi, police said.
