Praise be to Allah.
What is required of the business owner is to fear Allah, may He be exalted, with regard to his employees, and to pay them their salaries without deducting anything or delaying it. This is the requirement of the contract between him and them.
We have explained the prohibition on what some company owners do, who mistreat their employees by delaying their salaries, in the answer to question no. 60407.
We should also point out that if this refusal to pay the salaries is – indeed – because the company is unable to pay the salaries due to a lack of funds, then the company is excused, because Allah, may He be exalted, says (interpretation of the meaning): “And if someone is in hardship, then [let there be] postponement until [a time of] ease. But if you give [from your right as] charity, then it is better for you, if you only knew” [al-Baqarah 2:280]. But if the owner of the company is being heedless or taking too long to pay, then he is doing wrong, because the Prophet (blessings and peace of Allah be upon him) said: “For a rich man to delay payment is wrongdoing.” Narrated by al-Bukhaari (2400) and Muslim (1564).
What is meant by delaying payment here is delaying payment of what is due with no excuse.
This hadith indicates that if the delay in payment is on the part of a rich man, then this is wrongdoing and is haraam; if it is on the part of one who is poor and unable to pay, then it is not wrongdoing and it is not haraam.
Sharh Muslim by an-Nawawi.

And Allah is the source of strength.
