Salam Abdul Sami Bhai,
I have seen many instances where some local non-Muslims became Muslims at a local Mosque, many times at Friday Congregation or at Tableeghi Ijtama in US.
Only Allah (Subhan Wa Taala) (Eng. trans God (All praises belong to God) ) can guide a person. Its in Holy Quran as well. If Allah (S.W.T), wanted, Allah (S.W.T) would have made the whole world One Religion. Only few those are guided whom Allah (S.W.T) guides are shown the light of Faith. We can not say who will go to Hell or Heaven, only Allah (S.W.T) knows.
In your case, do the right thing. You are placed in a situation in which very few people are tested and given an opportunity to guide someone to Sirat-e-Mutaqeem or to discourage him.
Guide him to the local Mosque... AND also very important.. If he is serious and asks you some questions about how to make a Salaat, make some effort and teach him brother.
This way, Allah (S.W.T) is also giving you an opportunity to strengthen your Imaan. None of us have Strong Iman, even the Sahabaas, the companions of Prophet Muhammed (S.A.W), used to keep putting effort and saying how weak their Faith was... Even though, we all know they had the highest imaan / Faith.
[highlight]Another very important statement in Holy Quran by Allah (S.W.T).
Never dis-respect anyone due to their faith or belief. Whether Jew, Christian, Hindu, Jain, Parsi, or anyone... NEVER make redicule or fun of anyone. For they in retaliation will redicule you and get even. All are Allah (S.W.T)'s creations. By making fun of a person, you are making fun of Allah (S.W.T)'s creation / system. [/highlight]
Also in Quran, just because we are born in Muslim Family, and have Muslim names, does NOT mean we are TRUE believers and will be forgiven and go to Paradise right away. No.. Its not that easy... That's why we are here on EARTH to be tested.. individually.
We have been tested in the time that has elapsed, and only Allah (S.W.T) knows if we are TRUE believers, and whether we will be forgiven in the day of Judgement.
Every Act, Action, gesture we do, here is being recorded.
Including what I am typing here. I will be asked, did I truly believe what I typed. So, we can see how serious the Imaan and faith are.
The actions We do here are even more important.
Do not steal, do not rob, do not get involved in Bribes, Rishwat, Corruption, Adultry, Alcohol and non-halal food consumption, be kind to your Parents, neighbors, friends, fellow citizens...
And also, very critical, UPHOLD Justice and rule of Law... May Allah Bless us all, Ameen.
