Sheikh Hamad al-Haydarî
It is not permissible for you to eavesdrop upon them. Allah says: “O you who believe! Avoid much of suspicion for indeed some suspicion is sinful, and do not spy on one another.” [Sûrah al-Hujurât: 12]
The Prophet (peace be upon him) said: “Keep away from suspicion, for indeed suspicion is the falsest of speech. Do not eavesdrop or spy on one another. Do not rival and envy one another nor despise and shun one another. Be worshippers of Allah and be brothers as Allah has commanded you to be.” [Sahîh al-Bukhârî (5144) and Sahîh Muslim (2563) with the wording as related by Muslim]
Know, my dear brother, that if you fear Allah and follow His command and the command of His Messenger (peace be upon him) and refrain from eavesdropping, then Allah will suffice you, spare you from what you dislike, and make the outcome of your affairs a good one.
Moreover, you do not know if what they are saying about you is good or bad. It is also possible that they are mentioning your name in a matter that does not reflect upon you either positively or negatively.
Block the inroads that Satan is trying to make in order to destroy the brotherly relations between yourself and others. Keep your heart pure and spare your fellows from suspicion.
May Allah grant you success.
