Book: Kitab al-Ghaybah p 438.
Author: Abu Jafar at-Toose.
From Hasan ibn Ali: “This matter that you are waiting for, wouldn’t happen until some of you (shia) wouldn’t disown from others from you, and some of you would curse others from you, and some of you would spit in the faces of others from you, and some of you would testify to disbelief of others from you.”
We have already seen some shias accusing others from their sect in kufr. I suggest to those shias which would like to hasten appearance of their master – start making takfir of your brothers, spit in their faces. And may be your master would reappear again.
