Book 37, Number 6688:

Narrated Hudhayfah ibn al-Yaman:

Qays reported: I said to Ammar: What is your opinion about that which you have done in case (of your siding with Ali)? Is it your personal opinion or something you got from Allah"s Apostle?

Ammar said: We have got nothing from Allah"s Apostle which people at large did not get, but Hudhayfah told me that Allah`s Apostle (peace_be_upon_him) had especially told him amongst his Companion, that there are twelve hypocrites out of whom eight would not get into Paradise, until a camel would be able to pass through the needle hole. The ulcer would be itself sufficient (to kill) eight.

(So far as four are concerned, I do not remember what Shu"bah said about them.)

Narrated Jabir ibn Abdullah:

Allah"s Apostle (peace_be_upon_him) said: He who climbed this hill, the hill of Murar, his sins would be obliterated as were obliterated the sins of Banu Isra"il.

So the first to take their horses were the people of Banu Khazraj. Then there was a ceaseless flow of persons and Allah"s Apostle (peace_be_upon_him) said to them: All of you are those who have been pardoned except the owner of a red camel.

We came to him and said to him: You also come on, so that Allah"s Apostle (peace_be_upon_him) may seek forgiveness for you. But he said: By Allah, so far as I am concerned, the finding of something lost is dearer to me than seeking of forgiveness for me by your companion (the Prophet), and he remained busy in finding out his lost thing.

Narrated Jabir ibn Abdullah:

Allah"s Apostle (peace_be_upon_him) came back from a journey and as he was near Medina, there was such a violent gale that the mountain seemed to be pressed.

Allah"s Apostle (peace_be_upon_him) said: This wind has perhaps been made to blow for the death of a hypocrite, and as he reached Medina a notorious hypocrite from amongst the hypocrites had died.

Book 37, Number 6695:

Narrated Salamah ibn al-Akwa":

We went along with Allah"s Apostle (peace_be_upon_him) to visit a person suffering from fever. When I placed my hand upon him, I said: By Allah, I have never seen, till this day, a person running higher temperature than he.

Thereupon Allah"s Apostle (peace_be_upon_him) turning his face to his companions, said: May I not inform you of a severer temperature than this which these two persons would run on the Day of Resurrection? And they were two hypocrites riding upon the camel turning their back towards (the Muslims).

Book 37, Number 6696:

Narrated Abdullah Ibn Umar:

Allah"s Apostle (peace_be_upon_him) said: The similitude of a hypocrite is that of a sheep which roams aimlessly between two flocks. She goes to one at one time and to the other at another time.
