Those whom Allāh Almighty hates the most are those who go about committing calumny, who sever the ties between brothers, who look for fault in others" ( Al-`Awāli , Vol. 1, p. 106, tradition No. 21, and Ihyā Ulūm ad-Dīn , Vol. 3, p. 146).
The Messenger of Allāh (ص) also said once, "Shall I inform you about the worst evildoers among you?" People said, "Yes, indeed, O Messenger of Allāh!" He (ص) said, "They are the ones who walk about committing calumny, who spoil the good relationship between those who love each other, who seek to find fault even with the innocent" ( Ihyā Ulūm ad-Dīn , Vol. 3, p. 146. See also Al-Khisāl , Vol. 1, p. 86).
Abū Tharr has said, "The Messenger of Allāh (ص) has said that if someone articulates a word against a Muslim seeking to shame him without a just cause, Allāh will shame him in the fire on the Day of Judgment" ( Ihyā Ulūm ad-Dīn , Vol. 3, p. 147).
Abū al-Dardā' has said once that the Messenger of Allāh (ص) said, "If a man propagates a bad statement about someone who is guilty in order to defame him in this life, it will be incumbent upon Allāh, the most Exalted and the most Great, to penalize him for it on the Day of Judgment with the fire" ( Ihyā Ulūm ad-Dīn , Vol. 3, p. 147).
He (ص) has also been quoted as saying that when Allāh Almighty created Paradise, He said to it, "Speak!" It said, "Happy is anyone who enters me." The most Great One said, "I swear by My Exaltation and Greatness, eight categories of people shall find no room in you: None will reside in you if he is a habitual drinker, or one who insists on committing adultery, or one who goes around committing calumny, or one who has no concern about his honor, or one who acts [with others] like a policeman, or a homosexual, or one who severs his ties with his kin, or one who says, 'I pledge to Allāh to do such-and-such' but does not do it" ( Ihyā Ulūm ad-Dīn , Vol.
3, p. 147). The father of Ja`far (ع) is quoted as saying, "Paradise is prohibited from those who commit calumny, who slander others" ( Al-Kāfi , Vol. 2, p. 365). The father of Abdullāh (ع) cites the Commander of the Faithful (ع) saying, "The most evil persons among you are those who spread calumny by slandering, who separate loved ones from each other, who seek fault with the innocent" ( Al-Kāfi , Vol. 2, p. 369).
It has been narrated that Moses (ع) prayed for rain for the Israelites during a drought.
