Allāh ﷻ commands in the Holy Qur’ān to stay away from bad suspicion. Thinking badly occupies the mind and can make a person see good as bad. But the Prophet ﷺ also taught us to be careful, saying a believer is not bitten from the same hole twice. Allāh ﷻ gave you intelligence and the light of īmān, so use them and do not let people deceive you.
