Sir I no have viza I go Pakistan

It should be noted that after reviewing your inquiry and legal scrutiny we would like to inform you that
 travel to and from UAE and Pakistan are subject to government decisions

All nationals who are stucked in the UAE due to flight suspensions have been asked to register with their counsular services wich they are collecting data of the ones who want to travel back to their countries when the "special flights" will become operational.
Even that you have no visa you can still quit the country, since that the Holders of expired UAE visit visas should either leave the country by August 11, 2020 or can apply for a 1-month grace period,

They have 1 month (30-days) to leave as of July 12 to avoid fines,

But the ICA issued a new order, that they can renew the 30-day grace period one more time after August 11.

“As per the last amendments, it has been decided to grant entry permits and visit visa holders inside the country, a period of one month (30 days) to leave the country. The grace period is renewable one time by the authority, after which, the entry permit or visit visa holder needs to exit the country to avoid fines.”

The extension of the grace period would be done by the ICA.
