Does a 13-year-old who omits prayer out of shyness and embarrassment while visiting relatives cease to be a Muslim?

Whoever abandons one of the five prayers has committed a grave sin. Accountability begins with puberty. A Muslim is advised to maintain prayer at its prescribed time, even if they have not reached the age of accountability, and to feel more shame before Allah than before people. Indeed, it is hoped that they would command their relatives to pray if they are not praying. The majority of scholars hold that whoever abandons prayer without denial of its obligation does not become a disbeliever thereby.
