Whoever hates the Ahl al-Bayt will enter the Fire even if he prays and fasts

It is narrated from Sayyiduna Zayd bin Arqam (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I am leaving among you two weighty things (al-thaqalayn): the Book of Allah and my Ahl al-Bayt, and these two will never separate from each other until they come to me at the Pond (al-Kawthar)."
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "O Banu Abd al-Muttalib! I have asked Allah three things for you: that He keep firm those of you who stand steadfast, that He guide those of you who have gone astray, and that He grant knowledge to the ignorant among you. And I also asked Allah to make you generous, brave and merciful. So if a man were to stand between the Corner (al-Rukn) and the Station (al-Maqam), praying and fasting, and then meet Allah while he hates the Ahl al-Bayt of Muhammad (peace and blessings be upon him), he will enter Hell."
This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) looked at Sayyiduna Ali, Sayyidah Fatimah, Sayyiduna al-Hasan and Sayyiduna al-Husayn (may Allah be pleased with them) and said: "I declare war against whoever fights you, and there is peace for whoever makes peace with you."
This hadith is hasan (good) among the narrations of Imam Ahmad bin Hanbal from Talid bin Sulayman, for I have not found any other narration of his besides it. And it also has a supporting report (shahid) from the hadith of Sayyiduna Zayd bin Arqam (may Allah be pleased with him):
