Examples from the time of the Prophet

show us that some from amongst the people who were thought to have sincerely repented to Allah after foolishly apostasizing from Islam and were genuinely seeking to live in submission to Allah - were accepted back into the community, others were punished for their crimes, and in the time of the companions of the messenger of Allah, those who were believed to be false to Allah after apostasizing from the way of Allah and attempting to pretend that they were truly repentant were punished severely.
إِنَّ الَّذِينَ آمَنُواْ ثُمَّ كَفَرُواْ ثُمَّ آمَنُواْ ثُمَّ كَفَرُواْ ثُمَّ ازْدَادُواْ كُفْرًا لَّمْ يَكُنِ اللّهُ لِيَغْفِرَ لَهُمْ وَلاَ لِيَهْدِيَهُمْ سَبِيلاً {137
Verily, those who believe (in Allah), then deny/reject Allah, then believe (again), and (again) reject/deny, and go on increasing in denial; Allah will not forgive them, nor guide them on the (Right) Way.
Quran 4:137
There is a difference between minor sins, major sins, nifaqq, and kufr so please let none of us think for even a moment that anyone deceive Allah.
I posted that for clarification since it's on the forum - the shower part does not require an answer and it is neither lawful, nor funny to make eeman sound like light banter.
The Hypocrites are afraid lest a Sura should be sent down about them, showing them what is (really passing) in their hearts. Say: "Mock! But verily Allah will bring to light all that ye fear (should be revealed).
If you question them, they declare (with emphasis): "We were only talking idly and in play."
Say: "Was it at Allah, and His Signs, and His Messenger, that you were mocking?"
Make no excuses: you have rejected Faith after you had accepted it. If We pardon some of you, We will punish others amongst you, for they are guilty of crime.
From Quran, Chater 9, verses 64-66
