22/9. Chapter:
What Has Been Reported About Swearing That One Has Nothing To Do With Islam Or That One Belongs To Another Religion
Sunan Abi Dawud
حَدَّثَنِي أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا زَيْدُ بْنُ الْحُبَابِ، حَدَّثَنَا حُسَيْنٌ، - يَعْنِي ابْنَ وَاقِدٍ - حَدَّثَنِي عَبْدُ اللَّهِ بْنُ بُرَيْدَةَ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم : " مَنْ حَلَفَ فَقَالَ إِنِّي بَرِيءٌ مِنَ الإِسْلاَمِ فَإِنْ كَانَ كَاذِبًا فَهُوَ كَمَا قَالَ، وَإِنْ كَانَ صَادِقًا فَلَنْ يَرْجِعَ إِلَى الإِسْلاَمِ سَالِمًا " .
Narrated Buraydah ibn al-Hasib: The Prophet (ﷺ) said: If anyone takes an oath and says: I am free from Islam; now if he is a liar (in his oath), he will not return to Islam with soundness.
