Is music unanimously prohibited, and is talking to young men in writing or by voice online considered a major sin?

Scholars have unanimously agreed on the prohibition of listening to musical instruments, and the Hadith (definition) of the Prophet, peace and blessings be upon him, indicates their impermissibility. As for communication between the sexes via the internet, it is forbidden due to the corrupting influences it causes, and if it leads to something forbidden, then it is forbidden. Prohibited means take the ruling of their objectives, and they are forbidden even if they do not reach the level of a major sin. Lenience with minor sins turns them into major sins.
