What is the duty of Muslim students residing in France in introducing Islam to non-Muslims? And is this an obligation upon them even though they are not da'wah specialists? And how do they convey that? And how do they interact with non-Muslim neighbors?

Inviting people to Islam is an obligation upon all followers of the Prophet, peace and blessings be upon him, according to their capacity, for Allah Almighty says: "Say, 'This is my way: I invite to Allah with insight, I and those who follow me. And exalted is Allah; and I am not of those who associate others with Him.'"
