He found a winning lottery ticket; is it permissible for him to cash it in?
Question

                I was walking outside and foound a winning lottery ticket on the ground that nobody has claimed. Is it permissible for me to cash it in because i did not put any money or goods to purchase the ticket which is the definition of gambling. Please advise.
Praise be to Allah.
      The lottery is gambling, which is haraam. Allah, may He be 
      exalted, says in His Book (interpretation of the meaning):

    “O you who believe! Intoxicants (all kinds of alcoholic 
    drinks), and gambling, and Al‑Ansaab (stone altars for sacrifices to idols 
    etc), and Al‑Azlaam (arrows for seeking luck or decision) are an abomination 
    of Shaytaan’s (Satan’s) handiwork. So avoid (strictly all) that 
    (abomination) in order that you may be successful.

    91. Shaytaan (Satan) wants only to excite enmity and 
    hatred between you with intoxicants (alcoholic drinks) and gambling, and 
    hinder you from the remembrance of Allaah and from As‑Salaah (the prayer). 
    So, will you not then abstain?”

    [al-Maa’idah 5:60-61]. 

    If a Muslim finds a lottery ticket on the ground, then he has 
    not engaged in gambling, because he did not pay any money for this ticket, 
    but this does not mean that taking the money is permissible, because he will 
    be taking the money unlawfully. 

    What right does he have to take this money? 

    Taking money in this way comes under the general meaning of 
    the verse in which Allah says (interpretation of the meaning):

    “And eat up not one another’s property unjustly (in any 
    illegal way, e.g. stealing, robbing, deceiving)”

    [al-Baqarah 2:188]. 

    A lottery ticket is not a permissible means of earning 
    money. 

    And Allah knows best.
