It is narrated from Sayyiduna Mu’adh bin Jabal (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said to him: Shall I not tell you what is the foundation of the religion, its pillar, and its highest peak? I said: O Messenger of Allah! Certainly. He (peace and blessings be upon him) said: The foundation of the religion and its pillar is prayer, and its highest peak is jihad. Then he (peace and blessings be upon him) said: Shall I not also tell you about that thing which controls all of these? I said: Yes, O Prophet of Allah! In response, he (peace and blessings be upon him) held his blessed tongue and said: Restrain this over yourself. I said: O Messenger of Allah! Will we also be held accountable for what we say? He (peace and blessings be upon him) said: O Mu’adh! May your mother lose you, nothing throws people on their faces into the Fire except the harvest of their tongues.
