In a previous answer, you mentioned that whoever among the Jews and Christians hears the Message of Muhammad (peace and blessings of Allaah be upon him) and comes to know of it, then does not follow it, is a kaafir, and they will be dealt with as such in this world and in the Hereafter. As you know, in our country there are many Christians and followers of other religions. Is the fact that they are present in this Muslim country sufficient to convey the Message to them?
Praise be to Allaah.
The fact that they are present in a Muslim country means that they will be considered as being among those who have heard the Message of Muhammad (peace and blessings of Allaah be upon him), and the appropriate rulings will apply to them, because Allaah says (interpretation of the meaning):
“… this Qur’aan has been revealed to me that I may therewith warn you and whomsoever it may reach…” [al-An’aam 6:19]
And the Prophet (peace and blessings of Allaah be upon him) said: “By the One in Whose Hand is my soul, no one of this nation, Jew or Christian, will hear of me then die without believing in that with which I have been sent, but he will be one of the people of Hell.” (Narrated by Muslim).
