Saheeh (sound) hadeeths, Dought & Clear, - * The authenticity of the hadeeth about fighting the Jews

Is the hadeeth saheeh which says that there will come a day when the
Muslims will be victorious over the Jews, so that a rock beneath which
a Jew is hiding will call out, "There is a Jew underneath me, come and
kill him"?
Praise be to Allaah.
It was narrated that Ibn 'Umar (may Allaah be pleased with him) said:
"I heard the Messenger of Allaah (peace and blessings of Allaah be
upon him) say, 'The Jews will fight you and you will prevail over
them, then a rock will say, "O Muslim, here is a Jew behind me, (come
and) kill him."'" (Narrated by al-Bukhaari, no. 3593).
It was also narrated from Ibn 'Umar (may Allaah be pleased with him)
that the Messenger of Allaah (peace and blessings of Allaah be upon
him) said. "The Jews will fight you and you will prevail over them
until a rock will say, "O Muslim, here is a Jew behind me, (come and)
kill him."'" (narrated by Ahmad and al-Tirmidhi, who said, this is a
saheeh hasan hadeeth).
And it was narrated that Ibn 'Umar (may Allaah be pleased with him)
said: "I heard the Messenger of Allaah (peace and blessings of Allaah
be upon him) say: 'The Dajjaal will come down to this pond at
Marriqanaat (a valley near Madeenah), and most of those who go out to
follow him will be women, such that a man will go back to his wife,
mother, daughter, sister or (paternal) aunt and will tie them up lest
they go out to join him. Then Allaah will grant the Muslims victory
over him, and they will kill him and his party, until a Jew will hide
beneath a tree or a rock, and the tree or rock will say, 'Here a Jew
beneath me, (come and) kill him.'" (Narrated by Ahmad in hisMusnad).
This was also narrated by Ibn Maajah from Abu Umaamah al-Baahili from
the Prophet (peace and blessings of Allaah be upon him) concerning the
Dajjaal.
And Allaah is the Source of strength. May Allaah bless our Prophet
Muhammad and his family and companions, and grant them peace.
