Are the ahaadeeth about matters of the unseen revelation (wahy) from Allaah?

 

I
have a question regarding hadith. I know the Prophet (saaw) never spoke
from his own desires about the deen so how did he know information about
stuff like the signs of the dat of judgement and so on? Did Allah (swt)
tell him all these things?
Please clearify this matter for me. Thank you

Praise be to Allaah. 

Everything that the
Messenger
(peace and blessings of Allaah be upon him) has told us about
the unseen, past, present and future, such as the beginning of creation, the
resurrection, Paradise, Hell, the signs of the Hour, the angels and the
Prophets, all of that is by revelation (wahy)
from Allaah, as Allaah says (interpretation of the meaning):

 “Nor does he speak of (his own)
desire. It is only a Revelation revealed” (al-Najm 53:3-4)

 “This
is of the news of the Unseen which We reveal unto you (O Muhammad)” [Hood
11:49]

 “Say
(O Muhammad): ‘I don’t tell you that with me are the treasures of
Allaah, nor (that) I know the Unseen; nor I tell you that I am an angel. I
but follow what is revealed to me.’” [al-An’aam 6:50]

 Hence
it is obligatory to believe everything that Allaah has told the Messenger

(peace and blessings of Allaah be upon him) concerning the unseen and
other matters, for he is the one who tells the truth and is to be believed.
Whoever disbelieves him, even if it is with regard to only one report that
he knows to be sound (saheeh), becomes an apostate thereby, if he is Muslim.
