It is narrated regarding Hazrat Ya'la (may Allah be pleased with him) that once he was sitting with Ziyad. A man was brought to Ziyad who had given some testimony. Ziyad altered his testimony and said, "I will cut off your tongue." Upon hearing this, Hazrat Ya'la (may Allah be pleased with him) said, "Shall I not tell you a hadith I heard from the Prophet (peace and blessings be upon him)? I heard the Prophet (peace and blessings be upon him) say that Allah Almighty says: 'Do not mutilate My servants.'" Upon this, Ziyad let him go.
