Calling Maintenance Workers Who Do Not Pray

Question:
Most of the maintenance and cleaning workers in the ministries are Muslims, but they do not attend the congregational prayer; in fact, most of them do not pray at all, and some only pray on Friday. I have seen this, experienced it, and looked into it. They need a full introduction to Islam, either by sending guides from your side or by setting up small libraries containing books in multiple languages that introduce them to Islam. Each ministry should be sent a guide or books according to the nationalities present there. This is my opinion on one hand, and my question on the other: in my capacity as , I am unable to explain things to them in Arabic due to differences in dialect or language. Is there any sin on me if I leave them to their own devices, given that I have feared Allah as much as I was able?

Answer:
The obligatory duty upon you is to do what you can, and to seek the help of your brothers who understand the language. Your brother who understands the language should go with you so that the call to Islam is achieved by everyone through cooperation. Likewise, you should advise those among them who do pray. This is a necessity in dealing with people in the path of Allah; it is necessary to generalize the effort, because there are many of them. So, may Allah will it, the effort must be generalized so that they are directed to good, guided to good, and the relevant authorities become aware of them, directing them to good and teaching them. We have da'is (preachers) who are committed to this matter, and the women here are doing so in their languages and in every place. This is a matter of importance that requires attention. Every group should be called to Islam in their own language. We ask Allah to help us in this and to guide the Muslims to fulfill their duty. This is not limited to the employee; anyone who has insight and the ability should exert what they can in this path.
