Malik on Speech: Sins of the tongue become weakness in the body

Al-Munawi reported: Malik ibn Dinar, may Allah have mercy on him, said, “If you see hardness in your heart, weakness in your body, and deprivation in your provision, then know that you have spoken about what is not your concern.”

عن المناوي قَالَ مَالِك بْن دِينَار رحمه الله إِذَا رَأَيْتَ قَسَاوَةً فِي قَلْبِكَ وَوَهْنًا فِي بَدَنِكَ وَحِرْمَانًا فِي رِزْقِكَ فَاعْلَمْ أَنَّكَ تَكَلَّمْتَ فِيمَا لَا يَعْنِيكَ
