Is absentmindedness during the Friday sermon considered "laghw" (idle talk/distraction)?

Listening to the preacher on Friday is obligatory, and anything that contradicts this listening is not permissible to do intentionally. Wandering off, being negligent, and being absent-minded during the sermon are considered contrary to listening, so it is not permissible to do so intentionally. For this reason, a Muslim should not occupy their heart with anything during the sermon, because the purpose of listening is to pay attention to what the preacher mentions and to be admonished by it.
