وَعَنْ عَبْدِ اَللَّهِ بْنِ عَمْرِوٍ رَضِيَ اَللَّهُ عَنْهُمَا قَالَ: { جَاءَ أَعْرَابِيٌّ إِلَى اَلنَّبِيِّ – صلى الله عليه وسلم -فَقَالَ: يَا رَسُولَ اَللَّهِ! مَا اَلْكَبَائِرُ?. … فَذَكَرَ اَلْحَدِيثَ, وَفِيهِ قُلْتُ: وَمَا اَلْيَمِينُ اَلْغَمُوسُ? قَالَ: ” اَلَّذِي يَقْتَطِعُ مَالَ امْرِئٍ مُسْلِمٍ, هُوَ فِيهَا كَاذِبٌ” } أَخْرَجَهُ اَلْبُخَارِيُّ. 1 . 1 – صحيح. رواه البخاري ( 6920 ).

Narrated ‘Abdullah bin ‘Amr (RA): A desert Arab came to the Prophet (صلى الله عليه وسلم) and said, “O Allah’s Messenger, what are the major sins?” The narrator reported the Hadith and it contains: “The false oath.” It contains also: I asked, “What is the false oath?” The Prophet (صلى الله عليه وسلم) replied, “It is that (oath) by which one takes possession of the property of a Muslim person, while he is lying.” [al-Bukhari reported it].
