Swearing That One Has Nothing To Do With Islam
Sunan an-Nasai
أَخْبَرَنَا الْحُسَيْنِ بْنُ حُرَيْثٍ، قَالَ حَدَّثَنَا الْفَضْلُ بْنُ مُوسَى، عَنْ حُسَيْنِ بْنِ وَاقِدٍ، عَنْ عَبْدِ اللَّهِ بْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ قَالَ إِنِّي بَرِيءٌ مِنَ الإِسْلاَمِ فَإِنْ كَانَ كَاذِبًا فَهُوَ كَمَا قَالَ وَإِنْ كَانَ صَادِقًا لَمْ يَعُدْ إِلَى الإِسْلاَمِ سَالِمًا " .
It was narrated from 'Abdullah bin Buraidah that his father said: "The Messenger of Allah said: 'Whoever says: I have nothing to do with Islam, if he is lying then he is as he said, and if he is telling the truth, his Islam will not be sound.'"
