Is it considered eavesdropping to listen to the answer to a question a girl asked another, when you had the same question yourself?

Listening to others' conversations without their consent is forbidden, based on the Prophet's (peace be upon him) saying: "Whoever listens to the conversation of a people who dislike that, or who flee from him, molten lead will be poured into his ears on the Day of Resurrection." However, if the speakers do not dislike it, then there is no harm. And spying on people must be avoided. We also remind of the prohibition of studying in co-educational schools and the necessity of avoiding conversation with female students unless there is an urgent need.
