She went to a fortunate teller to find out who the thief was and he accused her brother
Question

                A box was stolen from my sister and her husband and children in which there was a lot of money. My sister’s husband was broken-hearted and the people told him about a Shaykh who was said to be able to relieve distress and find lost items by Allaah’s Leave. He (that Shaykh) asked about me, with a cigarette in his hand, and he said to me: I saw you last night, your name is So and so, and you are the thief. This is my work and my source of income, and I will get 25 percent of the stolen goods. Tell me and admit that you are the only thief that everyone is looking for. There was a lengthy discussion between me and him, and I swore by Allaah that I was innocent of what he said, and Allaah is witness to what I said. Please advise me, may Allaah reward you, please relieve me of the wrong and claims that are surrounding me.  I am afraid of turmoil among my relatives because injustice leads to a lot of bas consequences.
Praise be to Allah.
    Firstly: 

    The one who claims to know where stolen things are and who 
    the thieves are by means of secret things that the people do not know is one 
    of two things: a fortune-teller to whom the devils come, or a liar who makes 
    the people think that he knows these things in order to consume their wealth 
    unlawfully.  

    Whatever the case, it is not permissible to go to these 
    people and to ask them or believe them, no matter how righteous they may 
    appear to be, because the Prophet  (peace and blessings of Allaah be 
    upon him) said: “Whoever goes to a fortune-teller and asks him about 
    something, his prayers will not accepted for forty days.” Narrated by Muslim 
    (2230). 

    And he  (peace and blessings of Allaah be upon him) said: 
    “Whoever has intercourse with a menstruating woman or with a woman in her 
    back passage, or goes to a fortune-teller and believes what he says, has 
    disbelieved in that which Allaah revealed to Muhammad  (peace and 
    blessings of Allaah be upon him).” Narrated by Ahmad (9779), Abu Dawood 
    (3904), al-Tirmidhi (135) and Ibn Maajah (936); classed as saheeh by 
    al-Albaani in Saheeh Ibn Maajah. 

    Al-Baghawi (may Allaah have mercy on him) said: The 
    fortune-teller is the one who claims to have knowledge of things by means of 
    some information from which he figures out where stolen things are or where 
    lost items are etc. Quoted in al-Zawaajir ‘an Iqtiraaf al-Kabaa’ir 
    (2/178) 

    Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) said: 
    The fortune-teller: it was said that he is the soothsayer, who is the one 
    who foretells the future. 

    And it was said that it is a general term referring to 
    soothsayers, astrologers, geomancers and their ilk who claim to have 
    knowledge of the unseen by means of some knowledge and information that they 
    use. This is a more general meaning which is indicated by the derivation of 
    the word, as (the Arabic word) ‘arraaf (meaning fortune-teller) is derived 
    from the word ma’rifah (knowledge) so it applies to everyone who deals in 
    these matters and claims to have knowledge of them. End quote from 
    al-Qawl al-Mufeed ‘ala Kitaab al-Tawheed (2/48). 

    One of those who have repented from fortune-telling and 
    soothsaying said that he used to seek the help of the jinn in order to find 
    out from them details of what was going on in the house of the one whose 
    property was stolen, and his situation with his relatives and neighbours, 
    and his friends and enemies, and sometimes he would blame someone who was 
    under suspicion. 

    Even if we assume that the fortune-teller is able to point to 
    the real thief and bring the property back by means of his contact with the 
    jinn, it is not permissible to go to him and ask him anything, because of 
    the ahaadeeth quoted above. 

    Secondly: 

    Some scholars are of the view that the one who claims to have 
    knowledge of stolen items or that the jinn tell him about that is a kaafir. 
    Ibn Nujaym (may Allaah have mercy on him) said, discussing the things that 
    constitute kufr: Going to a soothsayer and believing him when he says ‘I 
    know where stolen items are’ or ‘I speak on the basis of what the jinn tell 
    me’. End quote from al-Bahr al-Raa’iq (5/130). As for his saying ‘I 
    speak on the basis of what the jinn tell me’ being kufr, that is because the 
    jinn, like humans, have no knowledge of the unseen, as Allaah says 
    (interpretation of the meaning): 

    “Then when We decreed death for him [Sulaymaan (Solomon)], 
    nothing informed them (jinn) of his death except a little worm of the earth 
    which kept (slowly) gnawing away at his stick. So when he fell down, the 
    jinn saw clearly that if they had known the Unseen, they would not have 
    stayed in the humiliating torment”

    [Saba’ 34:14]

    This was stated in the commentary on al-Bahr al-Raa’iq. 

    So asking a fortune-teller or soothsayer about anything is 
    haraam, and that includes asking him about lost or stolen items, or asking 
    him about a disease and the remedy for it. 

    The scholars of the Standing Committee for Issuing Fatwas 
    were asked: Sometimes we lose some money or gold in our house, and we 
    believe that it has been stolen, so we go to someone who is known as a 
    mukhbir (‘the one with the news’), and tell him about that, and he promises 
    us something good, and sometimes we find the lost item, and sometimes we 
    don’t. What is the ruling on our going to these people? 

    They replied: It is not permissible for you to go to him 
    because he is a soothsayer, and it was narrated in a saheeh report that the 
    Prophet  (peace and blessings of Allaah be upon him) forbade going to 
    soothsayers and their ilk, and asking them and believing them. End quote 
    from Fataawa al-Lajnah al-Daa’imah (1/410). 

    Thirdly: 

    The one who has gone to this fortune-teller and asked him 
    something has to repent to Allaah, may He be exalted, by regretting what he 
    has done, resolving not to do it again, and not accusing anyone of stealing 
    on the basis words of the fortune-teller and his helpers among the jinn, 
    because the jinn tell lies, and they may accuse someone who is innocent so 
    as to cause trouble among the Muslims. Repentance in this case is required 
    from the one who went to the fortune-teller and asked him, and of the one 
    who told him to do that, because both have fallen into sin. Please see 
    question no. 32863 for information on repenting from asking and believing 
    fortune-tellers. 

    The Muslim should turn to Allaah and ask Him to solve 
    problems and difficulties, for all things are in His Hand, may He be 
    glorified, as He says (interpretation of the meaning): 

    “Is not He (better than your gods) Who responds to the 
    distressed one, when he calls on Him, and Who removes the evil, and makes 
    you inheritors of the earth, generations after generations? Is there any 
    ilâh (god) with Allaah? Little is that you remember!”

    [al-Naml 27:62]

    And Allaah knows best. 

    This applies to your sister and her husband, and also applies 
    to you. You should turn to Allaah and ask Him to relieve you of this 
    accusation and wrong. 

    We advise your sister and her husband, and anyone who has 
    anything to do with this matter, not to accuse anyone on the basis of the 
    words of a charlatan or fortune-teller, because accusing someone who is 
    innocent is a serious matter. The basic principle is that he is innocent and 
    free of guilt. The Prophet  (peace and blessings of Allaah be upon him) 
    said: “Whoever says of a believer something that is not true, Allaah will 
    cause him to dwell in the mud of khabaal until he stops saying that.” 
    Narrated by Abu Dawood 5129 from Ibn ‘Umar (may Allaah be pleased with him); 
    classed as saheeh by al-Albaani in Saheeh Abi Dawood. 

    Mud of khabaal refers to mud and mire and what comes from the 
    sweat of the people of Hell. 

    May Allaah help us all to do that which He loves and which 
    pleases Him. 

    And Allaah knows best.
