Money transfer from Pakistan to Riyadh

For personal transfers, you can use western union.  The limit is $3000 per day per person.   You need to go to their agent offices - see details below.

To send money from an agent location in Pakistan, you must be present in-person and you must provide:

Your original and valid government-issued photo ID (CNIC, NICOP, Passport)
Your full name as it appears on your photo ID
Your occupation
The receiver’s full name
The receiver’s address (where applicable)
The relationship with the receiver
The purpose of the transaction
The receiver’s bank account details (if sending money to a bank account)
Additional information if required by the agent

Thank you so much for your response.
Do you know if there is a way you can transfer that money to your bank account from your bank's mobile app?
I know it works in some countries but don't know about banks here in riyadh

You asked from Pakistan TO Riyadh.  I answered that.

From Riyadh to Pakistan is easier and most banks allow for transfers through online banking / mobile apps.  Varies bank to bank.
