Arabic (Original)
حَدَّثَنَا يَحْيَى بْنُ وَاضِحٍ أَبُو تُمَيْلَةَ أَخْبَرَنِي حُسَيْنُ بْنُ وَاقِدٍ قَالَ سَمِعْتُ ابْنَ بُرَيْدَةَ يَقُولُ سَمِعْتُ أَبِي يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ قَالَ إِنِّي بَرِيءٌ مِنْ الْإِسْلَامِ فَإِنْ كَانَ كَاذِبًا فَهُوَ كَمَا قَالَ وَإِنْ كَانَ صَادِقًا فَلَنْ يَرْجِعَ إِلَى الْإِسْلَامِ.
English Translation
Yahya ibn Wadih Abu Tumaylah told us: Husayn ibn Waqid informed me: I heard Ibn Buraydah say: I heard my father say: I heard the Messenger of Allah, peace and blessings be upon him, say: Whoever says, I am free of Islam - if he is lying, then he is as he said, and if he is truthful, he will never return to Islam.
