[Machine] The Messenger of Allah ﷺ was asked about a man who claims to be a Jew, Christian, or someone who is not a Muslim, but he swears by Allah when making an oath and then breaks it. He replied that the expiation for breaking an oath is required. This narration has no basis in the Hadith of Az-Zuhri or others. Sulaiman ibn Abi Dawud al-Harrani attributed it to himself, but it is a fabricated hadith that has been weakened by scholars who have abandoned it.  

سُئِلَ رَسُولُ اللهِ ﷺ عَنِ الرَّجُلِ يَقُولُ هُوَ يَهُودِيٌّ أَوْ نَصْرَانِيٌّ أَوْ بَرِيءٌ مِنَ الْإِسْلَامِ فِي الْيَمِينِ يَحْلِفُ عَلَيْهِ فَيَحْنَثُ؟ قَالَ كَفَّارَةُ يَمِينٍ فَهَذَا لَا أَصْلَ لَهُ مِنْ حَدِيثِ الزُّهْرِيِّ وَلَا غَيْرِهِ تَفَرَّدَ بِهِ سُلَيْمَانُ بْنُ أَبِي دَاوُدَ الْحَرَّانِيُّ وَهُوَ مُنْكَرُ الْحَدِيثِ ضَعَّفَهُ الْأَئِمَّةُ وَتَرَكُوْهُ
