Another Person's Faith

Comments on the exchange of accusations and insults between some people :  

I don't think it is permissible for any of us to declare any verdict about another person's faith. We cannot see in anybody's heart, and just because they profess different beliefs from ours, it does mean that they are bad or we are good. We are all taking this exam of life, and we do not know what we or they will do with the rest of the life ahead of us. 

A few verses to think about: 

O you who believe[d]! When you go forth in (the) way (of) Allah then investigate, and (do) not say to (the one) who offers to you (a greeting of) peace, "You are not a believer," seeking transitory gains (of) the life (of) the world, for with Allah (are) booties abundant. Like that you were before, then Allah conferred favor upon you; so investigate. Indeed, Allah is of what you do All-Aware. [http://islamawakened.com/quran/4/94/] 

Indeed, those who divide their religion and become sects, you are not with them in anything. Only their affair (is) with Allah, then He will inform them of what they used to do. [http://islamawakened.com/quran/6/159/] 

Indeed, Allah, with Him (is the) knowledge (of) the Hour and He sends down the rain, and knows what (is) in the wombs. And not knows any soul what it will earn tomorrow, and not knows any soul in what land it will die. Indeed, Allah (is) All-Knower All-Aware. [http://islamawakened.com/quran/31/34/]  

May Allah guide us all.
