You cannot delete a message once it has been sent. But, if you accidentally sent a message to the wrong person and immediately realize it, there is something your can do to delete the message before someone reads it.
Immediately turn off the cellular data and Wi-Fi. The fastest way to block any internet connection is by enabling airplane mode, which can be reached easily from the notification bar (both on iPhone and Android or any other devices that have the notification bar).
After disabling the internet connection, you should see a red exclamation point next to the message if you did it on time. This indicates that the message was blocked.The next step is to click on the image to bring up the pull-down menu and click on Delete. Just one more click on Delete and the file will be permanently canceled from WhatsApp, without anyone reading it.
