Is it obligatory for us to call the disbelievers who live among Muslims to the truth and advise them?

Question : The disbelievers who are among them. It is obligatory for him to speak to me. May Allah reward you.

Answer : It is obligatory. How? It is obligatory that we call to Islam, even the disbelievers who are among us, such as workers and others. This is especially the case for the one who works with them a lot, for he is able to call them to the truth and explain the Islamic religion. Then, if they are guided, it is for them and for him; and if they are not guided, it is for him and against them, in any case. For he may recite it but not know its meaning. But it is good for the one who is among them and mixed with them to call them little by little. And he should explain to them, if he is able, with rational evidence that the religion of Islam is the truth.
