Does anybody know how to hack WhatsApp messages?
when I sent a message "Hi" at 4.00 pm after a half hour I need to change that message to "Hello" at the same time on the receiver side.

No way you can achieve this without having full command execution on the victim device.
I remember doing this a few years ago by editin the SQLite db in the /data/data/com.whatsapp/databases path but can't tell if this does still work.
