Sahih al-Bukhari, Hadith 6882 ⓘ

Narrated Ibn `Abbas: The Prophet said, "The most hated persons to Allah are three: (1) A person who deviates from the right conduct, i.e., an evil doer, in the Haram (sanctuaries of Mecca and Medina); (2) a person who seeks that the traditions of the Pre-lslamic Period of Ignorance, should remain in Islam (3) and a person who seeks to shed somebody's blood without any right."

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي حُسَيْنٍ، حَدَّثَنَا نَافِعُ بْنُ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ ‏ "‏ أَبْغَضُ النَّاسِ إِلَى اللَّهِ ثَلاَثَةٌ مُلْحِدٌ فِي الْحَرَمِ، وَمُبْتَغٍ فِي الإِسْلاَمِ سُنَّةَ الْجَاهِلِيَّةِ، وَمُطَّلِبُ دَمِ امْرِئٍ بِغَيْرِ حَقٍّ لِيُهَرِيقَ دَمَهُ ‏" ‏‏.‏
