It is narrated from Ibn Abi Hudhail (may Allah have mercy on him) that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) went with one of his companions to visit a sick person. When they entered the house, that companion began to look here and there. Sayyiduna Abdullah (may Allah be pleased with him) said to him: By Allah! If both your eyes were gouged out, that would have been better for you.

It is narrated from Nafi' (may Allah have mercy on him) that some people from Iraq came to Sayyiduna Ibn Umar (may Allah be pleased with them both), and they saw a gold necklace on the neck of one of his maidservants (slave-girls), so they began to look at each other. Sayyiduna Ibn Umar (may Allah be pleased with them both) said: "You people’s eyes are very sharp when it comes to seeing evil."

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him), he said: There is no good in idle talk.

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The worst and most wicked people of my Ummah are those who talk excessively, speak with wide open mouths, and speak with their mouths full. And the best people of my Ummah are those who have the best character."

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Among the worst of people is the one who displays two-faced behavior; he says one thing to one group and another to another group."

It is narrated from Sayyiduna Ammar bin Yasir (may Allah be pleased with him) that I heard the Prophet (peace and blessings of Allah be upon him) say: "Whoever is two-faced (deceitful) in this world will have two tongues made of fire on the Day of Resurrection." Then a heavyset man passed by, and the Prophet (peace and blessings of Allah be upon him) said: "He is one of them."

It is narrated from Sayyida Aisha (may Allah be pleased with her) that a man sought permission to enter upon the Prophet (peace and blessings be upon him), so the Prophet (peace and blessings be upon him) said: "Give him permission to enter, he is a bad man of his tribe." So when he entered, the Prophet (peace and blessings be upon him) spoke to him gently. I said: O Messenger of Allah! You said what you said about this man, then you spoke to him gently? The Prophet (peace and blessings be upon him) said: "O Aisha! The worst of people is the one whom people avoid because of his foul language and bad speech."

It is narrated from Sayyiduna Imran bin Husain (may Allah be pleased with them) that he said: The Prophet (peace and blessings of Allah be upon him) said: "Modesty brings nothing but good." Bashir bin Ka'b said: It is written in wisdom that modesty brings seriousness, and tranquility also comes from modesty. Sayyiduna Imran (may Allah be pleased with him) said to him: I narrate to you the hadith of the Messenger of Allah (peace and blessings of Allah be upon him), and you tell me things from your scriptures?

It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both), he said: Indeed, modesty and faith are joined together, so when one is taken away, the other is also taken away.

It is narrated from Sayyiduna Abu Bakr (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "Modesty is part of faith, and the person of faith will be in Paradise. Foul language is from harshness, and the harsh person will be in Hell."
