The ruling on greeting disbelievers as a means of calling to Allah

Question:
May Allah reward you, Your Eminence, father. The questioner asks: How do we call disbelievers to Allah through admonition or by reminding them of the miracles of the Prophet (peace and blessings be upon him) and the virtues of Islam? And what is the ruling on greeting them as a means of da'wah?

Answer:
It is not permissible to initiate the salam with them, but if they greet you, you return the salam. As for calling them, explaining the virtues of Islam, and explaining the miracles of the Messenger (peace and blessings be upon him), this is a required matter. This is a required matter so that Allah may guide whom He wills from among them, and so that the argument is established against whoever does not accept after the explanation.
