The Whatsapp app does a daily backup of the messages and stores them on the phone for when cases like these happen and this is where you can Restore your whatsapp chat history. Around 4:00 in the morning, when you are generally sleeping, WhatsApp makes the copy and notifies you in the user's profile.

As explained before, WhatsApp makes a daily copy of security and from there will recover the chat or message that we have deleted. For that you need to uninstall the application
To Recover Whatsapp Chat History, you have to do the route:
Settings/Applications/WHATSAPP/Uninstall
Once done you have to re-install the app from the Google Play Store.
In that installation process the system will ask if you want to recover old chats and there you have to say yes.
