Hadith In Muslim (57f) That A Believer Is Not A Believer When He Commit Sins
Partially yes. But doing such a sinful act even for the first time is a denial to God and faith in him. If he doesn’t repent after his act this makes the denying the faith as he doesn’t seems to have any care for the hereafter, unless he repents.
You are right but I think “denial of god” is not the right word in every case. Suppose a person was not a concious muslim and this led him to drink wine regularly but when he realized it, he was already addicted. Alcohol is a dangerous addiction. And then his attitude will decide after his realization. If he contiues to do so without any care, then it will show that he doesn’t seem to have any care for hereafter, but if he takes steps to stop it, it doesn’t show an arrogant atttitude. Another case, is that if a person is a concious muslim then did such an act and did not even repent, this shows the denial of God’s command, unless he repents. And this hadith is also refering to those whose attitude is just like that of a kafir ?. And that’s why “repentence maybe accepted after that” is also mentioned in this hadith. So the person who commits such acts and does not repent is showing the same attitude of kafir who knows truth but denies it deliberately. Once a kafir changes his atttitude of arrogance and accepts the truth , he is no longer a kafir.Similarly once such a muslim repents ,he is no longer having the same attitude as a kafir.
