I know someone who is a convert alhamduliah, he travelled abroad to gain knowledge a year after converting, and alhamduliah he removed all those that were not good for him in his deen.
But now 3 years later, his going back on everything that he has been against. For example, Facebook: he never liked it for the fact that it allowed gender interaction and he is now on Facebook and adding all his old friends that are non-Muslim, and also sin a lot astaghfirallah. May Allah guide them to Islam.
He also added a few girls including a girl he had strong desires for and was in a past relationship with before converting, they are now speaking via Facebook; I don't know what's being said but I'm afraid this brother is going off track. I don't want to judge because he may be giving dawah, allowing his old friends to understand, but allahu aalam.
I mean my question is what do I do? Should I speak to this brother?
Could it mean that he is going off track because of what he is doing and this girl situation?
