My nephew is comimg for umrah whi is 13 years old.Please advise me wearing Ihram is essentials for him.
If your nephew is 13 years old then he has most likely already reached puberty and therefore he is considered an adult in Shariah.
If he has not reached puberty then he has certainly reached the age of Murahiq who is close to being an adult.
Your nephew should wear the same Ihram as an adult would such as yours. There will be nothing different in his method of Ihram. He will wear Ihram like an adult and he would perform all the required acts of Tawaf as an adult.
And Allah knows best.
