بسم الله الرحمن الرحيم
(Fatwa: 859/795/N=1434)
When you performed ghusl once properly i.e. you poured water to each and every part of your body then there is no need of ghusl again after four or five minutes when your body was dried. Do not repeat your ghusl due to baseless doubt.
Allah knows Best!
