If a person believes that God knows about his life, both the apparent and the secrets, then such a person will always say the right word when he speaks about someone. Otherwise, he will stay quiet. This is the meaning of the hadith. The belief that God knows the hidden and the apparent of my life will stop you from speaking badly about someone, at home or in society. The option before us is to either speak nicely of others or remain silent.
When a person has faith in God, faith in accountability in the Hereafter, faith that God is listening to him, then he will never speak badly. He will speak good words or else remain silent. فَلْيَقُلْ خَيْرًا أَوْ لِيَصْمُتْ (Sahih al-Bukhari 6018) If a person believes that God knows about his life, both the apparent and the secrets, then such a person will always say the right word when he speaks about someone. Otherwise, he will stay quiet. This is the meaning of the hadith. The belief that God knows the hidden and the apparent of my life will stop you from speaking badly about someone, at home or in society. The option before us is to either speak nicely of others or remain silent. The third option of speaking badly about someone doesn’t exist.
