Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "Whoever swears by 'Lat' and 'Uzza', he should recite 'La ilaha illallah', and whoever says to his companion: 'Come, let me gamble with you,' he should give something in charity."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings of Allah be upon him) saying: "A man utters a word, regarding which he perceives no harm, but because of that word he will keep falling into Hell for seventy years."

Sayyiduna Abu Huraira (may Allah be pleased with him) narrates: He heard the Prophet Muhammad (peace and blessings be upon him) saying: "A man (sometimes) utters a word because of which he will fall into Hell deeper than the distance between the east and the west."

Sayyiduna Abu Huraira (may Allah be pleased with him) narrates this statement of the Noble Prophet (peace and blessings of Allah be upon him): "Sometimes a servant utters a word which he does not consider to be significant, but because of it he will fall into the depths of Hell deeper than the distance between the east and the west."

Sayyiduna Duhak bin Abu Jubair رضي الله عنه narrates: In the time of ignorance, people used to have titles. The Prophet Muhammad صلى الله عليه وسلم called a person by his title. The Prophet صلى الله عليه وسلم was informed, "O Messenger of Allah (صلى الله عليه وسلم)! This person dislikes it." So Allah Almighty revealed this verse: "Do not call each other by bad names. After believing, calling someone a sinner is a bad name." The narrator states: It was the practice of the Ansar that whoever Allah willed, they would give charity and donations, until once a famine struck them, so they stopped doing so. Then Allah Almighty revealed this verse: "And spend in the way of Allah and do not throw yourselves into destruction with your own hands, and do good; indeed, Allah loves those who do good."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said: "No person should ever say, 'May Allah disfigure your face and the face that resembles your face,' because Allah the Exalted created Sayyiduna Adam (peace be upon him) in His own image."

(Imam Ibn Hibban, may Allah have mercy on him, says:) What is meant here is the appearance of the person to whom it was said: 'May Allah disfigure your face,' who is from the offspring of Sayyiduna Adam (peace be upon him). And the evidence that the address here is to the children of Adam and not to anyone else is the statement of the Noble Prophet (peace and blessings be upon him): "And the face that resembles your face," because the face of Sayyiduna Adam (peace be upon him) resembles the appearance of his children."

Sayyiduna Jundub bin Abdullah Bajali (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "A man said: By Allah, Allah will not forgive so-and-so. So Allah the Exalted said: I have forgiven so-and-so and have nullified your deeds."

Sayyiduna Dhamdham bin Jaus (may Allah be pleased with him) narrates: I entered the mosque of the Prophet (peace and blessings of Allah be upon him) and there was an elderly man whose hair was dyed yellow and whose teeth were extremely bright. With him was a young man who was very handsome and youthful. The old man said: O Yamami, come forward. Never say to anyone, "May Allah not forgive you." By Allah, Allah will never admit you to Paradise. I asked, "Who are you? May Allah have mercy on you." He replied: "I am Abu Hurairah." I said: "Such words are sometimes used by one of us for his wife or servant when he expresses anger at them." Sayyiduna Abu Hurairah (may Allah be pleased with him) said: "Do not say this, because I heard the Prophet (peace and blessings of Allah be upon him) say: 'Among the Children of Israel there were two men who were brothers to each other. One of them was devoted to worship and the other was a sinner. The worshipper saw the sinner committing a sin and said to him: 'Reduce this.' The other man replied: 'Leave this matter between me and my Lord.' The Prophet (peace and blessings of Allah be upon him) said: The worshipper repeated his words to him, and the other man gave the same reply: 'Leave me and my Lord.' Until one day, the worshipper saw him committing a sin and considered his sin to be great. He said: 'Woe to you! Refrain from sinning.' The other man said: 'Leave me and my Lord. Were you sent as a watcher over me?' The worshipper said: 'By Allah, Allah will never forgive you.' (The narrator is unsure, perhaps these were the words.) Or he said: 'Allah will never admit you to Paradise.' (The Prophet, peace and blessings of Allah be upon him, said:) Then an angel was sent to both of them, who took their souls. They both appeared before Allah, the Exalted. The Lord asked the worshipper: 'Are you a scholar, or do you have power over what is in My control, or do you prevent My mercy from reaching My servant?' (Then He said to the sinner:) 'Go to Paradise.' (The narrator says: That is, Allah said this to the sinful person.) And to the other He said: 'Take him to Hell.' (The Prophet, peace and blessings of Allah be upon him, or perhaps Sayyiduna Abu Hurairah, may Allah be pleased with him, said:) 'By Him in Whose hand is my soul, he uttered a word that destroyed his world and his Hereafter.'"

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "No person should say: 'May time be ruined,' because Allah Almighty is the One who controls time."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings of Allah be upon him) say: "Allah Almighty says: Man abuses Time, whereas I am Time; night and day are in My Hand of Power."
