Nasibi
Nasibi (Collective Plural Arabic: الناصبة, translit. an-Nāsibiyyah; Multiple Plural Arabic: نواصب, translit. Nawāsib; Singular Arabic: ناصبي, translit. Nāsibi) is an Arabic term meaning "those who have hatred". The term is often used in a pejorative sense by Shi'a Muslims against Sunnis, to those who they believe hate the Ahl Al-Bayt (the Household of the Islamic prophet Muhammad) or their followers. The term is usually used to refer to Sunnis; however, there are also Shia hadith in which The Twelve Imams stated that some hypocrite Shias and Shia break-off sects are also Nasibis.
Shia Hadiths Regarding Nasibis
A narration reports:حدثنا محمد بن على ماجيلويه - رضى الله عنه - قال: حدثني عمى محمد بن أبي القاسم، عن محمد بن على الكوفي، عن ابن فضال عن المعلى بن خنيس، قال: سمعت أبا عبد الله عليه السلام يقول: ليس الناصب من نصب لنا أهل البيت لانك لاتجد أحدا يقول: أنا ابغض محمدا وآل محمد، ولكن الناصب من نصب لكم وهو يعلم أنكم تتولونا أو تتبرؤون من أعدائنا، وقال عليه السلام: من أشبع عدوا لنا فقد قتل وليا لناNarrated Muhammad bin Ali Majiluwaih (ra) who said: Told me my uncle Muhammad bin abi al Qasim, from Muhammad bin Ali al Kufi, from ibn Fudhaal from al Mu'alla bin Khunais, who said: I heard Aba AbdAllah (as) saying: "The nasib is not one who acknowledges hatred for us Ahl Al-Bayt, for indeed you will not find anyone saying "I most hate Muhammad and his pure family, but instead the nasib is one who has hatred for you people while he knows that you people love us or hate those from our enemies." And [Imam (as)] said: "Whoever fed our enemy, then he has killed a friend of ours."
A narration reports:و أهل مدينة تدعى سجستان هم لنا أهل عداوة و نصب و هم شر الخلق و الخليقة عليهم من العذاب ما على فرعون و هامان و قارونAnd the people of the place called Sistan, they are people that are enemies and have nasb (hate) for us (Ahl Al-Bayt [AS] and their loyal Shiah), and they are an evil creation. Upon them is the torment (of hell), like the torment upon Far’oun (Pharaoh), Haman and Qharoun.
