Additional Sessions Judge Reetesh Singh also allowed prosecution plea to grant them more time to complete their investigation in the case.
The court allowed prosecution's plea and sent the accused persons -- Mohd Sajid, Shakir and Sameer -- for further jail term after they were produced before the court.
The court had earlier sent the accused to police custody on the prosecution's plea that their custodial interrogation was required to crack their Delhi module.
Special Cell teams had conducted the raids in Delhi and Uttar Pradesh in a joint operation of Delhi Police and a central intelligence agency.
All the three accused were suspected to be members of a sleeper unit of the terror outfit, police alleged.
