He wants to give a piece of land to his children, sons and daughters; how should he divide it among them?
Question

                How does my grandfather go about if he wants to distribute his land to his children (two sons and three daughter)but some of the land isnt as profitable as another part of it right now.
Praise be to Allah.
      It is obligatory to be fair and just when giving to one’s 
      children, because of the report narrated by al-Bukhaari (2587) and Muslim 
      (1623) from al-Nu‘maan ibn Basheer (may Allah be pleased with him), that 
      the Prophet (blessings and peace of Allah be upon him) said: “Fear Allaah 
      and treat your children fairly.” 

    The scholars of the Standing Committee for Issuing Fatwas 
    said: 

    It is not permissible for parents to differentiate between 
    the children in giving gifts, because the Prophet (blessings and peace of 
    Allah be upon him) said: “Fear Allaah and treat your children fairly”, and 
    because that causes envy, hatred, resentment and grudges, and severs ties 
    between siblings, and all of that is contrary to the aims of sharee‘ah which 
    came to encourage harmony, close ties, friendship and warm feelings between 
    relatives and family members. End quote. 

    Fataawa al-Lajnah al-Daa’imah, 
    16/225 

    If the children include both males and females, then treating 
    them fairly and justly means giving each male the share of two females, as 
    in the case of dividing inheritance, because there is nothing more just and 
    fair than the division ordained by Allah, may He be exalted. 

    The scholars of the Standing Committee for Issuing Fatwas 
    said: 

    Whoever gives gifts to his children when still alive must 
    treat them all fairly and justly, so he should give the male the share of 
    two females, as in the way of dividing inheritance that is enjoined by 
    Allah, may He be exalted, and because ‘Ata’ said: They used not to divide it 
    except in accordance with the book of Allah, may He be exalted. End quote. 

    Fataawa al-Lajnah al-Daa’imah, 
    16/213 

    Shaykh Saalih al-Fawzaan said: 

    What is required of the father is to treat his children 
    fairly and justly when giving, so he should give each male the share of two 
    females, following the way of division ordained by Allah, may He be 
    glorified and exalted. End quote. 

    Al-Muntaqa min Fataawa al-Fawzaan, 
    87/14 

    Based on that, your grandfather should divide the land 
    between his children, giving each male the share of two females, and in 
    doing so he should pay attention to its value. 

    If his children willingly agree to give some of them more 
    than others, there is nothing wrong with that. 

    And Allah knows best.
