"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.'"
قَالَ رَسُولُ اللَّهِ ﷺ مَنْ قَالَ إِنِّي بَرِيءٌ مِنَ الإِسْلاَمِ فَإِنْ كَانَ كَاذِبًا فَهُوَ كَمَا قَالَ وَإِنْ كَانَ صَادِقًا لَمْ يَعُدْ إِلَى الإِسْلاَمِ سَالِمًا
