Is it permissible for an employee to read Qur’aan during work hours?
Question

                What is the ruling on an employee reading Qur'aan during official work hours at the company’s expense?.
Praise be to Allah.If that is 
    at the company’s expense – as mentioned in the question – then it is not 
    permissible, because the employee has agreed with the workplace that he will 
    do the work that he is entrusted with, adhering to the daily work hours. So 
    if he does not work complete hours, or falls short in his work, that is 
    forbidden, because Allaah says (interpretation of the meaning): 
“O you 
    who believe! Fulfil (your) obligations”

    [al-Maa'idah 5:1]
And the 
    Prophet  (peace and blessings of Allaah be upon him) said: “The Muslims 
    are bound by their conditions.” Narrated by Abu Dawood (3594), classed as 
    saheeh by al-Albaani in Saheeh Abi Dawood. 
But if his 
    reading Qur'aan does not affect his work performance, there is nothing wrong 
    with that in sha Allaah. 
Shaykh Ibn 
    ‘Uthaymeen (may Allaah have mercy on him) was asked: If an employee has 
    finished his work and he wants to make use of the time by reading Qur’aan or 
    reading something useful, or even wants to take a nap so that he can rest a 
    little, is there anything wrong with that? 
He replied: 
There is 
    nothing wrong with that so long as he has completed the work that he was 
    entrusted with. But if he is negligent or falls short in doing his work, 
    then it is haraam for him and it is not permissible. As for taking a nap, 
    there is no concession with regard to that, because he will have no control 
    over himself and he may sleep and miss his work without realizing. End quote
