What is the ruling on a husband speaking with his wife on the phone about sexual matters that may lead to ejaculation during a period of separation due to travel?

There is no harm in a husband speaking with his wife about matters of intimacy, provided that no one else can hear them and that the conversation does not lead to anything forbidden. If ejaculation occurs merely from the conversation, there is no harm. However, if it occurs through touching with the hand or similar means, it is a forbidden masturbation. The questioner is advised to strive to have his wife live with him or to return to his country. Otherwise, he must fast, guard his hearing and sight, occupy his time with beneficial activities, associate with righteous people, and supplicate frequently.
