Salam alaikum, we all remember shia habit of usage hadith: Whoever hate Ali is Munafiq, and his lover is Believer.
No we want to introduce this believer for shias.
Saduq in his “Ilal ush Sharae” (p 145) narrated that Iblis said:
.. No I am not his Mawali, and not from his shias, BUT I LOVE HIM, no one hates him (Ali) except I am partner in his children and his property..
So, exactly as shias say that each one who hates Ali (r.a) was munafiq, we call them to accept Iblis as a believer.
