Arabic (Original)
حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ مِنْ كِتَابِهِ حَدَّثَنِي حُسَيْنٌ حَدَّثَنِي ابْنُ بُرَيْدَةَ عَنْ أَبِيهِ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ حَلَفَ أَنَّهُ بَرِيءٌ مِنْ الْإِسْلَامِ فَإِنْ كَانَ كَاذِبًا فَهُوَ كَمَا قَالَ وَإِنْ كَانَ صَادِقًا فَلَنْ يَرْجِعَ إِلَى الْإِسْلَامِ سَالِمًا.
English Translation
Zayd ibn al-Hubab told us from his book: Husayn told me: Ibn Buraydah told me, from his father, who said: The Messenger of Allah, peace and blessings be upon him, said: Whoever swears that he is free of Islam - if he is lying, then he is as he said, and if he is truthful, he will never return to Islam safely.
