Is it permissible to delay payment of salaries to employees?
Question

                I work in a company as an accountant, and all the financial transactions and cheques pass through me. The owner of the company pays zakaah but he delays payment of salaries to employees by three months. Is that permissible?.
Praise be to Allah.
    It is not permissible to delay payment of salaries to 
    employees beyond the time when they are due, which is when the work is 
    completed or at the end of the agreed-upon period. If the agreement is that 
    the salary be paid monthly, then it must be paid to the worker at the end of 
    each month; delaying it with no excuse is regarded as unfair and unjust. 
    Allaah says (interpretation of the meaning): 

    “Then if they give suck to the children for you, give them 
    their due payment”

    [al-Talaaq 65:6]

    So Allaah commanded that they be given their payment as soon 
    as the work is done.  

    Ibn Maajah (2443) narrated that ‘Abd-Allaah ibn ‘Umar (may 
    Allaah be pleased with him) said: The Messenger of Allaah  (peace and 
    blessings of Allaah be upon him) said: “Give the worker his wages before his 
    sweat dries.” Classed as saheeh by al-Albaani in Saheeh Ibn Maajah. 
What this means to 
    hastening to give him his dues as soon as the work is done. Similarly, when 
    the agreed-upon period ends (which is one month in the case of most 
    employees nowadays), then it is obligatory to hasten to give him his dues. 

    Al-Manaawi said in Fayd al-Qadeer: 

    It is haraam to delay and postpone when one is able to pay. 
    The command to give it to him before his sweat dries is a metaphor for the 
    obligation to pay him as soon as the job is done, even if he does not sweat, 
    or if he sweated and it has dried. End quote. 

    The company owner’s delay in paying the salaries is 
    wrongdoing which makes his honour and punishment permissible, as the Prophet 
     (peace and blessings of Allaah be upon him) said: “Withholding of 
    payment by a rich man is wrongdoing.” Narrated by al-Bukhaari (2400), Muslim 
    (1564). 

    And the Prophet  (peace and blessings of Allaah be upon 
    him) said: “If one who can afford it delays payment, his honour and 
    punishment become permissible.” Narrated by Abu Dawood (3682), al-Nasaa’i 
    (4689) and Ibn Maajah (2427), classed as hasan by al-Albaani in Irwa’ 
    al-Ghaleel, 1434. 
What is meant by his 
    honour becoming permissible is that one may say, “So and so delayed paying 
    me and he wronged me.” Punishing him means detaining him. This is how it was 
    interpreted by Sufyaan and others. 

    The Standing Committee was asked about a boss who did not 
    give his workers their salaries until they traveled to their homelands once 
    every year or two, and the workers agreed to that because they have no 
    choice, job opportunities are few, and they need the money. 

    They replied: What this boss should do is to give his workers 
    their salaries at the end of every month, as is the custom among people 
    nowadays. But if there is an agreement and they accept that the salary will 
    be paid all together after one or two years, there is nothing wrong with 
    that, because the Prophet  (peace and blessings of Allaah be upon him) 
    said in a saheeh hadeeth: “The Muslims are bound by their conditions.” End 
    quote.

Based on the above, you 
    should advise the company owner and explain to him that it is haraam to 
    delay the employees’ salaries and it is haraam to harm them. 
And Allaah knows 
    best.
