It is not common man’s responsibility to convey the message of Islam to the whole world. But he is responsible for his surroundings as expounded in Meezan in the chapter: “Preaching Obligation of an Individual” that

“It is evident from the nature and scope of this preaching as mentioned in these verses that the preacher and the preached are not distinct from one another. Every person at all times acts as a preacher as well as an addressee to this preaching. This is evident by the words used by the Qur’an: بَعْضُهُمْ أَوْلِيَاء بَعْضٍ (they are friends to one another). This responsibility should be discharged by a father towards his son and a son towards his father, a husband towards his wife and a wife towards her husband, a brother towards his sister and a sister towards her brother, a friend towards his friend and a neighbour towards his neighbour – in short, a person should discharge it towards every person who has an immediate relation with him. When he sees that someone among them has adopted an attitude which is contrary to the truth, he should try to urge him according to his knowledge, capacity and ability to mend his ways. It is quite possible that while at one time of the day we deliver some truth to a person, and at another time, he does this very service to us. Today, we may urge a person to the right way and tomorrow that person might urge us to the same. In short, a Muslim should keep discharging this duty in his immediate circle whenever he gets the opportunity.”
