Hadith.4956 - Al-Hasan ibn Mahbub narrated from Abdullah ibn Sinan, from Abu Hamzah, who said
I asked Abu Ja'far Imam Muhammad ibn Ali Al-Baqir (as), "What is the least form of (nasb) hostility (towards the Ahlulbayt (as))?"
Imam (as) replied: "It is when a man innovates something, and then loves because of it and hates because of it."
