Is it bad to turn the engine on and off frequently

[dr. d]

Im a Grab Driver and after I drop the passenger off I am turning off the engine to save fuel consumption, after 5-10 minutes I will start it again. Is this ok? Am I shortening any parts of my car? Please help, I will appreciate it very much.

i used to that with my diesel, during long stoplights.
