Renew passport

Any one pls answer

First of all, you chose to ask this question on the day of your travel itself and then posted a reminder barely two minutes after your initial post.  Your lack of planning is what landed you into this situation and unfortunately, no one here is paid to respond instantly.  Everyone does it whenever they have time.

Secondly, you didn't post any relevant details i.e. do you have a visa or an Iqama?

Because, if you have an Iqama, there is no need to renew your passport and you can do it when back.  If you have a visa, then you might want to renew your passport back home as embassies only cater to residents.
