If you have deleted WhatsApp messages from one contact, you may be able to recover them using the recovery process. If you have not deleted the messages, you can still recover them by following these steps:

  1. Log into your WhatsApp account and open the Messages app.
  2. Scroll down and find the message that you want to recover.
  3. Tap on it and select the “Recover” option.
  4. After recovering the message, you can use it again or store it in your contacts for future use.
